Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + +## Usage Example + + +{`pragma solidity ^0.8.30; + +import {IDiamondLoupeFacet} from "@compose/diamond-contracts/contracts/facets/DiamondLoupeFacet.sol"; + +contract DiamondLoupeConsumer { + IDiamondLoupeFacet diamondLoupeFacet; + + constructor(address _diamondAddress) { + diamondLoupeFacet = IDiamondLoupeFacet(_diamondAddress); + } + + function getAllFacets() public view returns (IDiamondLoupeFacet.Facet[] memory) { + return diamondLoupeFacet.facets(); + } + + function getFacetAddress(bytes4 _selector) public view returns (address) { + return diamondLoupeFacet.facetAddress(_selector); + } + + function getFacetSelectors(address _facet) public view returns (bytes4[] memory) { + return diamondLoupeFacet.facetFunctionSelectors(_facet); + } +}`} + + +## Best Practices + + +- Integrate `DiamondLoupeFacet` into your diamond to provide necessary introspection for developers and external tools. +- Call loupe functions with `view` or `pure` modifiers to avoid unnecessary gas costs. +- Cache frequently accessed loupe data in your own contracts if performance becomes a bottleneck, though direct calls are generally gas-efficient. + + +## Security Considerations + + +The `DiamondLoupeFacet` is a read-only facet.

Be cautious when granting broad roles, and always use `requireRole` at the entry point of functions that require specific permissions. The `renounceRole` function should be used with care, as it permanently removes the caller's access to a role.

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {IDiamondLoupeFacet} from "@compose/diamond-contracts/contracts/facets/DiamondLoupeFacet.sol"; - -contract DiamondLoupeConsumer { - IDiamondLoupeFacet diamondLoupeFacet; - - constructor(address _diamondAddress) { - diamondLoupeFacet = IDiamondLoupeFacet(_diamondAddress); - } - - function getAllFacets() public view returns (IDiamondLoupeFacet.Facet[] memory) { - return diamondLoupeFacet.facets(); - } - - function getFacetAddress(bytes4 _selector) public view returns (address) { - return diamondLoupeFacet.facetAddress(_selector); - } - - function getFacetSelectors(address _facet) public view returns (bytes4[] memory) { - return diamondLoupeFacet.facetFunctionSelectors(_facet); - } -}`} - - -## Best Practices - - -- Integrate `DiamondLoupeFacet` into your diamond to provide necessary introspection for developers and external tools. -- Call loupe functions with `view` or `pure` modifiers to avoid unnecessary gas costs. -- Cache frequently accessed loupe data in your own contracts if performance becomes a bottleneck, though direct calls are generally gas-efficient. - - -## Security Considerations - - -The `DiamondLoupeFacet` is a read-only facet. Its functions do not modify state and are generally considered safe.

The library enforces this, but explicit checks in calling facets can add an extra layer of safety. -- When resetting token-specific royalties using `resetTokenRoyalty`, be aware that it reverts to the default royalty settings. Ensure the default royalty is configured appropriately if this action is intended. -- Use custom errors or specific revert messages when calling functions to clearly indicate the reason for failure, especially during royalty setting operations. - - -## Integration Notes - - -The RoyaltyMod interacts with diamond storage to manage default royalty information and token-specific royalty configurations. Facets can access this module via its interface, and calls to functions like `royaltyInfo` will transparently query the appropriate storage slots within the diamond's storage layout. The `getStorage` function provides direct access to the internal storage struct, which is useful for advanced inspection or complex logic but should be used with caution to maintain storage hygiene. Changes to default royalties are immediately reflected in subsequent `royaltyInfo` calls for tokens without specific overrides. Token-specific royalties directly override the default for the specified token ID. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + +## Usage Example + + +{`pragma solidity ^0.8.30; + +import {IDiamondLoupeFacet} from "@compose/diamond-contracts/contracts/facets/DiamondLoupeFacet.sol"; + +contract DiamondLoupeConsumer { + IDiamondLoupeFacet constant DIAMOND_LOUPe = IDiamondLoupeFacet(0x1234567890abcdef1234567890abcdef1234567890); // Replace with actual diamond address + + function getFacetAddress(bytes4 _selector) external view returns (address) { + return DIAMOND_LOUPe.facetAddress(_selector); + } + + function getAllFacetAddresses() external view returns (address[] memory) { + return DIAMOND_LOUPe.facetAddresses(); + } + + function getFacetSelectors(address _facet) external view returns (bytes4[] memory) { + return DIAMOND_LOUPe.facetFunctionSelectors(_facet); + } + + function getAllFacets() external view returns (IDiamondLoupeFacet.Facet[] memory) { + return DIAMOND_LOUPe.facets(); + } +}`} + + +## Best Practices + + +- Integrate DiamondLoupeFacet into your diamond to enable discoverability and debugging of its functionalities. +- Use the provided functions to programmatically understand the diamond's architecture, especially during upgrades or when integrating new facets. +- Cache facet addresses locally if making frequent calls to the same facet to reduce gas costs. + + +## Security Considerations + + +DiamondLoupeFacet functions are read-only and do not modify state, posing minimal direct security risks.

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {IDiamondLoupeFacet} from "@compose/diamond-contracts/contracts/facets/DiamondLoupeFacet.sol"; - -contract DiamondLoupeConsumer { - IDiamondLoupeFacet constant DIAMOND_LOUPe = IDiamondLoupeFacet(0x1234567890abcdef1234567890abcdef1234567890); // Replace with actual diamond address - - function getFacetAddress(bytes4 _selector) external view returns (address) { - return DIAMOND_LOUPe.facetAddress(_selector); - } - - function getAllFacetAddresses() external view returns (address[] memory) { - return DIAMOND_LOUPe.facetAddresses(); - } - - function getFacetSelectors(address _facet) external view returns (bytes4[] memory) { - return DIAMOND_LOUPe.facetFunctionSelectors(_facet); - } - - function getAllFacets() external view returns (IDiamondLoupeFacet.Facet[] memory) { - return DIAMOND_LOUPe.facets(); - } -}`} - - -## Best Practices - - -- Integrate DiamondLoupeFacet into your diamond to enable discoverability and debugging of its functionalities. -- Use the provided functions to programmatically understand the diamond's architecture, especially during upgrades or when integrating new facets. -- Cache facet addresses locally if making frequent calls to the same facet to reduce gas costs. - - -## Security Considerations - - -DiamondLoupeFacet functions are read-only and do not modify state, posing minimal direct security risks.

Changes to the `ERC20Storage` struct definition or its storage slot will break compatibility and require diamond upgrades. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array.

Facets interacting with royalty logic should call the `IRoyaltyMod` interface, which is expected to be accessible through the diamond's storage mechanism (e.g., `_diamondStorage.getRoyaltyMod()`). The `royaltyInfo` function queries token-specific royalties first and falls back to default royalties if none are found for the given token. Storage for default royalties is managed in a predefined slot, while token-specific royalties are stored in a mapping accessible via the module. + + +

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {DiamondLoupeFacet} from "@compose/diamond-contracts/facets/DiamondLoupeFacet.sol"; -import {IDiamondLoupeFacet} from "@compose/diamond-contracts/facets/DiamondLoupeFacet.sol"; - -contract DiamondLoupeConsumer { - address immutable diamondAddress; - - constructor(address _diamondAddress) { - diamondAddress = _diamondAddress; - } - - function getDiamondFacets() external view returns (IDiamondLoupeFacet.Facet[] memory) { - DiamondLoupeFacet loupe = DiamondLoupeFacet(diamondAddress); - return loupe.facets(); - } - - function getFacetAddress(bytes4 _selector) external view returns (address) { - DiamondLoupeFacet loupe = DiamondLoupeFacet(diamondAddress); - return loupe.facetAddress(_selector); - } -}`} - - -## Best Practices - - -- Integrate `DiamondLoupeFacet` into your diamond to enable runtime inspection of its facets and function mappings. -- Use the provided functions to dynamically discover facet addresses and their supported selectors, facilitating interaction with various diamond functionalities. -- Ensure that `DiamondLoupeFacet` is initialized with the correct diamond storage pointers during deployment. - - -## Security Considerations - - -This facet is primarily for introspection and does not modify state.

The `getAccessControlStorage` and `getERC20Storage` functions provide direct access to these structs at their predefined diamond storage slots. The `checkTokenBridge` internal function specifically relies on the `AccessControlStorage` to verify the caller's `TrustedBridge` role. Facets implementing or interacting with this module should ensure they have the correct selectors registered for `crosschainBurn` and `crosschainMint` and that the diamond's storage layout accommodates these structs without conflicts. - - -

Facets using this module should declare a `uint256` variable (e.g., `_lock`) and associate it with the `LibNonReentrancy` library using `using LibNonReentrancy for uint256;`.

It is crucial that the storage slot for this lock variable is not shared or modified by other facets in a way that could compromise the lock's integrity.

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + +## Usage Example + + +{`pragma solidity ^0.8.30; + +import {DiamondLoupeFacet} from "@compose-protocol/diamond/contracts/facets/DiamondLoupeFacet.sol"; +import {IDiamondLoupe} from "@compose-protocol/diamond/contracts/interfaces/IDiamondLoupe.sol"; + +contract DiamondLoupeConsumer { + IDiamondLoupe public diamondLoupe; + + constructor(address _diamondAddress) { + diamondLoupe = IDiamondLoupe(_diamondAddress); + } + + function getAllFacets() public view returns (IDiamondLoupe.Facet[] memory) { + return diamondLoupe.facets(); + } + + function getFacetAddr(bytes4 _selector) public view returns (address) { + return diamondLoupe.facetAddress(_selector); + } + + function getFacetSelectors(address _facet) public view returns (bytes4[] memory) { + return diamondLoupe.facetFunctionSelectors(_facet); + } +}`} + + +## Best Practices + + +- Initialize the `DiamondLoupeFacet` during diamond deployment to ensure introspection functions are available from the start. +- Access `DiamondLoupeFacet` functions via the diamond proxy address to ensure all calls are routed correctly and adhere to diamond proxy logic. +- When querying for facet information, be mindful of gas costs, especially with `facets()` on diamonds with a very large number of facets and selectors; consider using more specific functions like `facetAddress()` or `facetFunctionSelectors()` when possible. + + +## Security Considerations + + +The `DiamondLoupeFacet` is generally read-only and does not modify state, thus posing minimal direct security risks.

Facets using this module will call its functions, which in turn access and modify the shared royalty storage. The `getStorage` function provides direct access to the `RoyaltyStorage` struct, which contains `defaultRoyalty` and `tokenRoyalties` mappings. Changes made through `setDefaultRoyalty` and `setTokenRoyalty` are immediately visible to subsequent calls to `royaltyInfo`. + + +

The `renounceRole` function should be used with caution as it permanently removes the caller's role.

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {DiamondLoupeFacet} from "@compose-protocol/diamond/contracts/facets/DiamondLoupeFacet.sol"; -import {IDiamondLoupe} from "@compose-protocol/diamond/contracts/interfaces/IDiamondLoupe.sol"; - -contract DiamondLoupeConsumer { - IDiamondLoupe public diamondLoupe; - - constructor(address _diamondAddress) { - diamondLoupe = IDiamondLoupe(_diamondAddress); - } - - function getAllFacets() public view returns (IDiamondLoupe.Facet[] memory) { - return diamondLoupe.facets(); - } - - function getFacetAddr(bytes4 _selector) public view returns (address) { - return diamondLoupe.facetAddress(_selector); - } - - function getFacetSelectors(address _facet) public view returns (bytes4[] memory) { - return diamondLoupe.facetFunctionSelectors(_facet); - } -}`} - - -## Best Practices - - -- Initialize the `DiamondLoupeFacet` during diamond deployment to ensure introspection functions are available from the start. -- Access `DiamondLoupeFacet` functions via the diamond proxy address to ensure all calls are routed correctly and adhere to diamond proxy logic. -- When querying for facet information, be mindful of gas costs, especially with `facets()` on diamonds with a very large number of facets and selectors; consider using more specific functions like `facetAddress()` or `facetFunctionSelectors()` when possible. - - -## Security Considerations - - -The `DiamondLoupeFacet` is generally read-only and does not modify state, thus posing minimal direct security risks. However, the information it provides can be critical for security audits and for understanding access control mechanisms implemented by other facets. Ensure that the diamond's upgradeability is managed securely, as changes to facet registration or function selector mappings could impact the integrity of the information returned by this facet. - - -

Ensure that the caller has sufficient allowance or ownership of the tokens being transferred. The `setApprovalForAll` function grants broad permissions to an operator, so callers should exercise caution when approving addresses. Reentrancy is not an explicit concern within the facet's core transfer logic as it relies on standard ERC-1155 patterns, but external contract interactions initiated by the diamond proxy should be audited for reentrancy risks. - - -

Facets using this module will call its functions, which in turn access and modify the shared royalty storage. The `getStorage` function provides direct access to the `RoyaltyStorage` struct, which contains `defaultRoyalty` and `tokenRoyalties` mappings. Changes made through `setDefaultRoyalty` and `setTokenRoyalty` are immediately visible to subsequent calls to `royaltyInfo`. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + +## Usage Example + + +{`pragma solidity ^0.8.30; + +import {IDiamondLoupe} from "@compose/diamond/contracts/facets/DiamondLoupeFacet.sol"; + +contract DiamondUser { + address immutable diamondAddress; + + constructor(address _diamondAddress) { + diamondAddress = _diamondAddress; + } + + function getDiamondFacets() public view returns (IDiamondLoupe.Facet[] memory) { + IDiamondLoupe loupe = IDiamondLoupe(diamondAddress); + return loupe.facets(); + } + + function getFacetAddrForSelector(bytes4 _selector) public view returns (address) { + IDiamondLoupe loupe = IDiamondLoupe(diamondAddress); + return loupe.facetAddress(_selector); + } +}`} + + +## Best Practices + + +- Integrate this facet into your diamond to enable runtime inspection of its deployed facets and their function mappings. +- Use the `facets()` function to retrieve a comprehensive list of all facets and their selectors for auditing or tooling purposes. +- Utilize `facetAddress(_selector)` to determine which facet handles a specific function call, aiding in debugging and external contract interactions. + + +## Security Considerations + + +This facet is read-only and does not modify state, making it inherently safe from reentrancy and state corruption attacks.

Facets interact with this module via its interface. Changes to default or token-specific royalties are immediately reflected when calling `royaltyInfo`. The `getStorage` function provides direct access to the module's storage struct, useful for off-chain indexing or advanced logic, but direct manipulation is discouraged in favor of the provided functions. + + +

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + +## Usage Example + + +{`pragma solidity ^0.8.30; + +import {IDiamondLoupe} from "./IDiamondLoupe.sol"; + +contract MyDiamond { + IDiamondLoupe constant diamondLoupe = IDiamondLoupe(address(this)); + + function getFacetAddresses() external view returns (address[] memory) { + return diamondLoupe.facetAddresses(); + } + + function getFacetSelectors(address _facet) external view returns (bytes4[] memory) { + return diamondLoupe.facetFunctionSelectors(_facet); + } + + function getAllFacets() external view returns (Facet[] memory) { + return diamondLoupe.facets(); + } +}`} + + +## Best Practices + + +- Deploy this facet as part of the initial diamond setup or upgrade process. +- Use the functions provided for debugging and understanding the diamond's composition, rather than for core application logic. +- Ensure the diamond's internal storage (`DiamondStorage`) is accessible to this facet for accurate data retrieval. + + +## Security Considerations + + +This facet is read-only and does not modify state, making it inherently safe from reentrancy attacks.

This includes mapping token IDs to owners, tracking token ownership for enumeration, and maintaining the total supply. Facets integrating with this module should be aware that state changes made through the module's functions (mint, burn, transferFrom) directly affect the diamond's storage and are immediately visible to all other facets. The order of storage variables within the `ERC721EnumerableStorage` struct is critical and must not be altered to maintain compatibility. + + +

The role of the entity granting roles should itself be strictly controlled. -- Use `grantRoleBatch` and `revokeRoleBatch` for efficiency when managing multiple accounts for the same role. -- Define roles using `bytes32` hashes for clarity and to prevent accidental role collisions. - - -## Security Considerations - - -Ensure that the caller has the necessary administrative privileges before granting or revoking roles. Reentrancy is not a concern for role management functions as they do not make external calls. Input validation is handled by the underlying diamond proxy logic; however, ensure correct role identifiers are used. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {IDiamondLoupe} from "./IDiamondLoupe.sol"; - -contract MyDiamond { - IDiamondLoupe constant diamondLoupe = IDiamondLoupe(address(this)); - - function getFacetAddresses() external view returns (address[] memory) { - return diamondLoupe.facetAddresses(); - } - - function getFacetSelectors(address _facet) external view returns (bytes4[] memory) { - return diamondLoupe.facetFunctionSelectors(_facet); - } - - function getAllFacets() external view returns (Facet[] memory) { - return diamondLoupe.facets(); - } -}`} - - -## Best Practices - - -- Deploy this facet as part of the initial diamond setup or upgrade process. -- Use the functions provided for debugging and understanding the diamond's composition, rather than for core application logic. -- Ensure the diamond's internal storage (`DiamondStorage`) is accessible to this facet for accurate data retrieval. - - -## Security Considerations - - -This facet is read-only and does not modify state, making it inherently safe from reentrancy attacks.

- **Title:** LibERC1155 — ERC-1155 Library Provides internal functions and storage layout for ERC-1155 multi-token logic. Thrown when insufficient balance for a transfer or burn operation. Uses ERC-8042 for storage location standardization and ERC-6093 for error conventions. This library is intended to be used by custom facets to integrate with ERC-1155 functionality. -
- -
- Signature: - -error ERC1155InsufficientBalance(address _sender, uint256 _balance, uint256 _needed, uint256 _tokenId); - -
- - -
- Thrown when array lengths don't match in batch operations. -
- -
- Signature: - -error ERC1155InvalidArrayLength(uint256 _idsLength, uint256 _valuesLength); - -
- - -
- Thrown when the receiver address is invalid. -
- -
- Signature: - -error ERC1155InvalidReceiver(address _receiver); - -
- - -
- Thrown when the sender address is invalid. -
- -
- Signature: - -error ERC1155InvalidSender(address _sender); - -
- - -
- Thrown when missing approval for an operator. -

- Signature: - -error ERC1155MissingApprovalForAll(address _operator, address _owner); - -
- - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {IERC1155Mod} from "@compose/modules/ERC1155Mod.sol"; - -contract MyDiamondFacet { - IERC1155Mod internal constant ERC1155 = IERC1155Mod(address(this)); - - function mintMyTokens(address to, uint256 id, uint256 amount) external { - ERC1155.mint(to, id, amount); - } - - function burnMyTokens(address from, uint256 id, uint256 amount) external { - ERC1155.burn(from, id, amount); - } - - function safeTransferMyTokens( - address from, - address to, - uint256 id, - uint256 amount, - bytes calldata data - ) external { - ERC1155.safeTransferFrom(from, to, id, amount, data); - } -}`} - - -## Best Practices - - -- Always validate `to` and `from` addresses before performing transfers or burns to prevent unintended state changes. -- Ensure the caller has sufficient approval or ownership before executing `safeTransferFrom` or `safeBatchTransferFrom`. -- Handle `ERC1155InsufficientBalance`, `ERC1155InvalidArrayLength`, and `ERC1155InvalidReceiver` errors gracefully in consuming facets. - - -## Integration Notes - - -The ERC1155Mod module interacts with a predefined storage slot within the diamond's storage layout to manage token balances, approvals, and URIs. Facets integrating this module will access this shared storage. The `getStorage` function provides direct access to this storage struct. Ensure that no other facets modify the relevant storage variables in ways that would violate ERC-1155 invariants. - - -

This includes mapping token IDs to owners, tracking token ownership for enumeration, and maintaining the total supply. Facets integrating with this module should be aware that state changes made through the module's functions (mint, burn, transferFrom) directly affect the diamond's storage and are immediately visible to all other facets. The order of storage variables within the `ERC721EnumerableStorage` struct is critical and must not be altered to maintain compatibility. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + +## Usage Example + + +{`pragma solidity ^0.8.30; + +import {IDiamondLoupe} from "@compose/diamond/facets/DiamondLoupe/IDiamondLoupe.sol"; + +contract DiamondConsumer { + IDiamondLoupe public diamondLoupeFacet; + + constructor(address _diamondAddress) { + diamondLoupeFacet = IDiamondLoupe(_diamondAddress); + } + + function getFacetAddresses() external view returns (address[] memory) { + return diamondLoupeFacet.facetAddresses(); + } + + function getFacetSelectors(address _facetAddress) external view returns (bytes4[] memory) { + return diamondLoupeFacet.facetFunctionSelectors(_facetAddress); + } + + function getAllFacets() external view returns (IDiamondLoupe.Facet[] memory) { + return diamondLoupeFacet.facets(); + } +}`} + + +## Best Practices + + +- Initialize the facet with the diamond's address to enable introspection. +- Use the returned data to verify diamond state or to dynamically route calls. +- Cache facet addresses and selectors locally if frequent querying is required to minimize on-chain calls. + + +## Security Considerations + + +This facet is primarily for read operations and does not directly manage state changes.

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {IDiamondLoupe} from "@compose/diamond/facets/DiamondLoupe/IDiamondLoupe.sol"; - -contract DiamondConsumer { - IDiamondLoupe public diamondLoupeFacet; - - constructor(address _diamondAddress) { - diamondLoupeFacet = IDiamondLoupe(_diamondAddress); - } - - function getFacetAddresses() external view returns (address[] memory) { - return diamondLoupeFacet.facetAddresses(); - } - - function getFacetSelectors(address _facetAddress) external view returns (bytes4[] memory) { - return diamondLoupeFacet.facetFunctionSelectors(_facetAddress); - } - - function getAllFacets() external view returns (IDiamondLoupe.Facet[] memory) { - return diamondLoupeFacet.facets(); - } -}`} - - -## Best Practices - - -- Initialize the facet with the diamond's address to enable introspection. -- Use the returned data to verify diamond state or to dynamically route calls. -- Cache facet addresses and selectors locally if frequent querying is required to minimize on-chain calls. - - -## Security Considerations - - -This facet is primarily for read operations and does not directly manage state changes.

Ensure that the storage slot for royalty data is not utilized by other facets to avoid conflicts. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + +## Usage Example + + +{`pragma solidity ^0.8.30; + +import {IDiamondLoupe} from "@compose/diamond/facets/DiamondLoupe/IDiamondLoupe.sol"; + +contract ExampleUsage { + IDiamondLoupe public diamondLoupe; + + constructor(address _diamondAddress) { + diamondLoupe = IDiamondLoupe(_diamondAddress); + } + + function getAllFacets() public view returns (IDiamondLoupe.Facet[] memory) { + return diamondLoupe.facets(); + } + + function getFacetAddress(bytes4 _selector) public view returns (address) { + return diamondLoupe.facetAddress(_selector); + } + + function getFacetSelectors(address _facet) public view returns (bytes4[] memory) { + return diamondLoupe.facetFunctionSelectors(_facet); + } +}`} + + +## Best Practices + + +- Integrate DiamondLoupeFacet into your diamond to enable runtime inspection of its components. +- Use the provided functions to verify facet registration and selector mappings during development and upgrades. + + +## Security Considerations + + +This facet is read-only and does not pose direct security risks.

The `LibNonReentrancy` library operates on a `uint256` variable within the facet's storage. This variable acts as the reentrancy guard flag. When a facet is deployed, this `uint256` storage slot should be initialized to `0` (its default state) to indicate that reentrancy is not currently active. The `enter` function will revert if the flag is already set (indicating reentrancy), and `exit` will reset the flag. Ensure the `uint256` variable used for the lock is declared in the facet and is not used for other purposes.

Facets interact with this module through its interface (`IAccessControlMod`). Functions like `grantRole`, `revokeRole`, and `hasRole` directly read from and write to the module's storage. The `requireRole` function acts as a guard, reverting execution if the calling account does not possess the specified role. Ensure the `AccessControlMod` is initialized correctly during the diamond deployment process. +This module requires dedicated storage slots for its role mapping and role admin mapping. Facets can interact with this module by calling its external functions. The `hasRole` and `requireRole` functions provide immediate feedback on an account's permissions. Changes to role assignments or role administration are persistent and visible across all facets interacting with the diamond.

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {IDiamondLoupe} from "@compose/diamond/contracts/facets/DiamondLoupeFacet.sol"; - -contract DiamondUser { - address immutable diamondAddress; - - constructor(address _diamondAddress) { - diamondAddress = _diamondAddress; - } - - function getDiamondFacets() public view returns (IDiamondLoupe.Facet[] memory) { - IDiamondLoupe loupe = IDiamondLoupe(diamondAddress); - return loupe.facets(); - } - - function getFacetAddrForSelector(bytes4 _selector) public view returns (address) { - IDiamondLoupe loupe = IDiamondLoupe(diamondAddress); - return loupe.facetAddress(_selector); - } -}`} - - -## Best Practices - - -- Integrate this facet into your diamond to enable runtime inspection of its deployed facets and their function mappings. -- Use the `facets()` function to retrieve a comprehensive list of all facets and their selectors for auditing or tooling purposes. -- Utilize `facetAddress(_selector)` to determine which facet handles a specific function call, aiding in debugging and external contract interactions. - - -## Security Considerations - - -This facet is read-only and does not modify state, making it inherently safe from reentrancy and state corruption attacks.

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - -## Usage Example - - -{`pragma solidity ^0.8.30; - -import {DiamondLoupeFacet} from "@compose/diamond-facets/DiamondLoupeFacet.sol"; - -contract MyDiamond { - DiamondLoupeFacet public diamondLoupeFacet; - - function initDiamond(address[] memory _facetAddresses, bytes4[][] memory _facetSelectors) external { - // ... deployment logic ... - diamondLoupeFacet = DiamondLoupeFacet(address(this)); - } - - // Example of calling a function from DiamondLoupeFacet - function getFunctionSelectors(address _facetAddress) external view returns (bytes4[] memory) { - return diamondLoupeFacet.facetFunctionSelectors(_facetAddress); - } - - function getAllFacets() external view returns ( - address[] memory facetAddresses, - address[] memory facetAddresses, - bytes4[][] memory facetSelectors - ) { - return diamondLoupeFacet.facets(); - } -}`} - - -## Best Practices - - -- Deploy DiamondLoupeFacet as part of the initial diamond deployment to ensure introspection capabilities are available from the start. -- Use the `facets` function to get a comprehensive view of the diamond's composition during development and auditing. -- Cache facet addresses and selectors in off-chain applications for performance, rather than repeatedly querying the diamond. - - -## Security Considerations - - -This facet is read-only and does not modify state, posing minimal direct security risks.

- **Title:** LibERC1155 — ERC-1155 Library Provides internal functions and storage layout for ERC-1155 multi-token logic. Thrown when insufficient balance for a transfer or burn operation. Uses ERC-8042 for storage location standardization and ERC-6093 for error conventions. This library is intended to be used by custom facets to integrate with ERC-1155 functionality. -
- -
- Signature: - -error ERC1155InsufficientBalance(address _sender, uint256 _balance, uint256 _needed, uint256 _tokenId); - -
- - -
- Thrown when array lengths don't match in batch operations. -
- -
- Signature: - -error ERC1155InvalidArrayLength(uint256 _idsLength, uint256 _valuesLength); - -
- - -
- Thrown when the receiver address is invalid. -
- -
- Signature: - -error ERC1155InvalidReceiver(address _receiver); - -
- - -
- Thrown when the sender address is invalid. -
- -
- Signature: - -error ERC1155InvalidSender(address _sender); - -
- - -

The `permit` function in this module validates the signature and updates the allowance, but it does not emit the `Approval` event. The facet calling the module's `permit` function must emit the `Approval` event to comply with ERC-20 and ERC-2612 standards. Storage for allowances is assumed to be managed by another facet that the `ERC20PermitMod` can interact with or that the calling facet updates based on the module's validation. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4.

If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6.

The facet itself does not handle access control; this is the responsibility of the diamond's upgradeable contract or a dedicated access control facet. Input validation for `tokenId` is crucial to prevent unexpected behavior or denial of service.

By using `enter` and `exit` within your facets, you ensure that a function cannot be re-entered before its initial execution completes, preventing common reentrancy vulnerabilities. --- @@ -96,31 +96,21 @@ error Reentrancy(); {`pragma solidity ^0.8.30; -import {LibNonReentrancy} from "@compose/contracts/src/modules/non-reentrancy/LibNonReentrancy.sol"; +import {LibNonReentrancy} from "@compose/contracts/src/libraries/LibNonReentrancy.sol"; contract MyFacet { using LibNonReentrancy for uint256; - uint256 internal _nonReentrancyState; + uint256 internal _nonReentrancyFlag; // Storage slot for the flag - /** - * @notice Performs an action that must not be reentrant. - */ - function sensitiveAction() external { - _nonReentrancyState.enter(); // Lock reentrancy + function doSomethingSensitive() external { + _nonReentrancyFlag.enter(); // Lock reentrancy - // Perform sensitive operations here... - // Example: emit Event("Operation started"); + // ... sensitive operations ... + // Example: calling an external contract that might call back + // address(externalContract).call{value: msg.value}(""); - _nonReentrancyState.exit(); // Unlock reentrancy - } - - /** - * @notice A function that might call sensitiveAction, but should be prevented from reentrancy. - */ - function attackerAction() external { - // This call will revert if sensitiveAction is already executing - sensitiveAction(); + _nonReentrancyFlag.exit(); // Unlock reentrancy } }`} @@ -128,19 +118,19 @@ contract MyFacet { ## Best Practices -- Always use `_state.enter()` at the beginning and `_state.exit()` at the end of functions that require reentrancy protection. -- Ensure the state variable used for non-reentrancy is initialized correctly and is unique to the function or context being protected. -- Handle the `Reentrancy` error explicitly in calling contracts or front-ends to provide clear feedback to users. +- Always call `enter` at the beginning of a function and `exit` at the end, ideally within a `try/finally` block to guarantee unlocking. +- Ensure the storage slot for the reentrancy flag is properly initialized and managed. It should typically be initialized to 0. +- Use the `Reentrancy` custom error for explicit error handling if needed, although the library handles reverts internally. ## Integration Notes -This module relies on a `uint256` storage slot to track the reentrancy state. Facets integrating this module must declare a `uint256` variable (e.g., `_nonReentrancyState`) and pass it by reference to the `enter` and `exit` functions. The state variable should be unique per protected context to avoid interference between different reentrancy guards. No specific slot ordering is mandated, but consistency within a facet is recommended. +This library operates on a `uint256` storage variable which acts as a flag. The `enter` function increments this flag, and `exit` decrements it. A reentrancy guard is active if the flag is greater than zero. Facets using this library must declare a `uint256` storage variable to hold the reentrancy flag and use `using LibNonReentrancy for uint256;` to access the `enter` and `exit` functions. The storage slot for this flag must be unique and managed according to Compose's storage slot allocation strategy.

- - - - - - -## Best Practices - - -- Initialize role administration and grant initial roles during diamond deployment. -- Use `grantRole` and `revokeRole` for individual account management. -- Utilize `grantRoleBatch` and `revokeRoleBatch` for efficient management of multiple accounts. -- Ensure that roles are properly defined and their admin roles are set to manage permissions effectively. - - -## Security Considerations - - -All state-changing functions (`setRoleAdmin`, `grantRole`, `revokeRole`, `grantRoleBatch`, `revokeRoleBatch`, `renounceRole`) require caller authorization, typically controlled by the role's admin role. The `requireRole` function reverts with `AccessControlUnauthorizedAccount` if the caller lacks the specified role. `renounceRole` reverts with `AccessControlUnauthorizedSender` if the caller is not the account attempting to renounce the role. Follow standard Solidity security practices for input validation. - - -

The owner of the diamond is responsible for authorizing all `diamondCut` operations. Ensure that facet addresses are valid and that function selectors are correctly mapped to prevent unexpected behavior. Initialization functions called via `_calldata` should be carefully audited for reentrancy and other vulnerabilities. Errors like `OwnerUnauthorizedAccount` and `InitializationFunctionReverted` indicate potential security issues. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - - - - -## Best Practices - - -- Call facet introspection functions through the diamond proxy to ensure consistent routing. -- Use `facets()` to get an overview of all deployed facets and their selectors. -- Utilize `facetAddress()` to determine which facet handles a specific function selector. - - -## Security Considerations - - -All functions in this facet are view functions and do not modify state.

- **Title:** LibERC1155 — ERC-1155 Library Provides internal functions and storage layout for ERC-1155 multi-token logic. Thrown when insufficient balance for a transfer or burn operation. Uses ERC-8042 for storage location standardization and ERC-6093 for error conventions. This library is intended to be used by custom facets to integrate with ERC-1155 functionality. -
- -
- Signature: - -error ERC1155InsufficientBalance(address _sender, uint256 _balance, uint256 _needed, uint256 _tokenId); - -
- - -
- Thrown when array lengths don't match in batch operations. -
- -
- Signature: - -error ERC1155InvalidArrayLength(uint256 _idsLength, uint256 _valuesLength); - -
- - -
- Thrown when the receiver address is invalid. -
- -
- Signature: - -error ERC1155InvalidReceiver(address _receiver); - -
- - -
- Thrown when the sender address is invalid. -
- -
- Signature: - -error ERC1155InvalidSender(address _sender); - -
- - -
- Thrown when missing approval for an operator. -

- - - - - - -## Best Practices - - -- Ensure receiver contracts implement the ERC1155TokenReceiver interface for safe transfers. -- Call `safeTransferFrom` or `safeBatchTransferFrom` for external transfers to ensure compatibility. -- Verify ownership and approvals before executing transfers to prevent reverts. - - -## Integration Notes - - -This module interacts with diamond storage at the position identified by `keccak256(\"compose.erc1155\")`. It utilizes the `ERC1155Storage` struct, which includes fields for `uri` and `baseURI`. All state modifications (minting, burning, URI setting) are performed directly on this shared storage, ensuring immediate visibility across all facets. - - -

Input validation is crucial for functions like `transferFrom`, `safeTransferFrom`, and `approve` to prevent issues such as transferring tokens to zero addresses or approving invalid operators. The `ownerOf` and `balanceOf` functions should be used to verify token ownership and existence before executing sensitive operations. Reentrancy is mitigated by the internal `internalTransferFrom` function, which follows the checks-effects-interactions pattern. - - -

It manages its state internally using a simple flag that is checked and updated by its `enter` and `exit` functions. Facets using this library maintain their own instance or call the library functions directly, ensuring reentrancy protection is localized to the calling facet's execution context. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + + + + +## Best Practices + + +- Ensure this facet is added to the diamond during initialization. +- Call `facetFunctionSelectors`, `facetAddresses`, and `facets` through the diamond proxy address. +- Use the returned information to understand the diamond's current composition and upgrade status. + + +## Security Considerations + + +All functions are view functions and do not modify state, thus carrying minimal security risk.

The `renounceRole` function checks that the caller is indeed the account attempting to renounce the role. Input validation is performed by underlying checks. Follow standard Solidity security practices. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - - - - -## Best Practices - - -- Ensure this facet is added to the diamond during initialization. -- Call `facetFunctionSelectors`, `facetAddresses`, and `facets` through the diamond proxy address. -- Use the returned information to understand the diamond's current composition and upgrade status. - - -## Security Considerations - - -All functions are view functions and do not modify state, thus carrying minimal security risk.

The `DiamondStorage` struct, although empty in the provided definition, represents the central storage for diamond-related information. Functions like `addFacets` and `diamondFallback` directly interact with this shared storage, making any modifications immediately visible to all facets that access the same storage slot. - - -

- **Title:** LibERC1155 — ERC-1155 Library Provides internal functions and storage layout for ERC-1155 multi-token logic. Thrown when insufficient balance for a transfer or burn operation. Uses ERC-8042 for storage location standardization and ERC-6093 for error conventions. This library is intended to be used by custom facets to integrate with ERC-1155 functionality. -
- -
- Signature: - -error ERC1155InsufficientBalance(address _sender, uint256 _balance, uint256 _needed, uint256 _tokenId); - -
- - -
- Thrown when array lengths don't match in batch operations. -

- - - - - - -## Best Practices - - -- Ensure ownership and approvals are checked before performing transfers. -- Handle `ERC1155InsufficientBalance`, `ERC1155InvalidArrayLength`, and `ERC1155MissingApprovalForAll` errors. -- Use `safeTransferFrom` and `safeBatchTransferFrom` for transfers to contract addresses to ensure receiver compliance. - - -## Integration Notes - - -This module manages ERC-1155 state within the diamond's storage. It uses a dedicated storage slot identified by `keccak256(\"compose.erc1155\")` to store its `ERC1155Storage` struct. Functions like `mint`, `burn`, and `transfer` directly interact with this shared storage. Any changes made through this module are immediately visible to all facets accessing the same storage slot. - - -

- - - - - - -## Best Practices - - -- Ensure that your facet implements appropriate access control before calling `mint`, `burn`, or `transferFrom`. -- Verify that the `ERC721EnumerableStorage` struct definition remains compatible across upgrades to prevent storage collisions. -- Handle the custom errors (`ERC721IncorrectOwner`, `ERC721NonexistentToken`, etc.) returned by the module's functions to provide clear feedback to users. - - -## Integration Notes - - -This module manages its state within the diamond storage pattern at the slot identified by `keccak256(\"compose.erc721.enumerable\")`. All functions interact directly with this storage slot. Changes made by any facet using this module (e.g., minting, burning, transferring) are immediately reflected in the shared storage and are visible to all other facets that access the same storage slot. - - -

Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. + + +{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} + + +**Parameters:** + + + +**Returns:** + + + +--- +### facetAddresses + +Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. + + +{`function facetAddresses() external view returns (address[] memory allFacets);`} + + +**Returns:** + + + +--- +### facets + +Gets all facets and their selectors.

For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. + + +{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} + + +**Returns:** + + + + + + +## Best Practices + + +- Ensure this facet is added to the diamond during initialization. +- Call facet inspection functions through the diamond proxy address. +- Verify storage compatibility before upgrading facets to maintain introspection integrity. + + +## Security Considerations + + +Follow standard Solidity security practices.

The `renounceRole` function should only be callable by the account whose role is being renounced. Input validation for account addresses and role bytes is critical. - - -

- - - - - - -## Best Practices - - -- Call `pauseRole` and `unpauseRole` only when necessary to temporarily restrict role functionality. -- Use `requireRoleNotPaused` to enforce active role checks, reverting with `AccessControlRolePaused` if the role is paused. -- Ensure the `AccessControlPausableMod` instance is correctly initialized and accessible by facets that require role pause management. - - -## Integration Notes - - -This module utilizes diamond storage at the `ACCESS_CONTROL_STORAGE_POSITION`, identified by `keccak25356("compose.accesscontrol")`. The `AccessControlPausableStorage` struct manages the pause state for roles. All functions are internal, directly interacting with this shared storage. Any facet that imports and calls functions on this module will see the updated pause status immediately due to the shared nature of diamond storage. - - -

Developers add this facet to understand and interact with a diamond's deployed facets. - ---- - -## Storage - -### FacetAndPosition - - -{`struct FacetAndPosition { - address facet; - uint32 position; -}`} - - ---- -### DiamondStorage - - -{`struct DiamondStorage { - mapping(bytes4 functionSelector => FacetAndPosition) facetAndPosition; - /** - * Array of all function selectors that can be called in the diamond. - */ - bytes4[] selectors; -}`} - - ---- -### Facet - - -{`struct Facet { - address facet; - bytes4[] functionSelectors; -}`} - - -### State Variables - - - -## Functions - -### facetFunctionSelectors - -Gets all the function selectors supported by a specific facet. Returns the set of selectors that this diamond currently routes to the given facet address. How it works: 1. Iterates through the diamond’s global selector list (s.selectors) — i.e., the selectors that have been added to this diamond. 2. For each selector, reads its facet address from diamond storage (s.facetAndPosition[selector].facet) and compares it to `_facet`. 3. When it matches, writes the selector into a preallocated memory array and increments a running count. 4. After the scan, updates the logical length of the result array with assembly to the exact number of matches. Why this approach: - Single-pass O(n) scan over all selectors keeps the logic simple and predictable. - Preallocating to the maximum possible size (total selector count) avoids repeated reallocations while building the result. - Trimming the array length at the end yields an exactly sized return value. - - -{`function facetFunctionSelectors(address _facet) external view returns (bytes4[] memory facetSelectors);`} - - -**Parameters:** - - - -**Returns:** - - - ---- -### facetAddresses - -Get all the facet addresses used by a diamond. This function returns the unique set of facet addresses that provide functionality to the diamond. How it works:** 1. Uses a memory-based hash map to group facet addresses by the last byte of the address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store the unique facet addresses, avoiding an extra memory allocation for the intermediate array. The selectors array is overwritten with facet addresses as we iterate. 3. For each selector, looks up its facet address and checks if we've seen this address before by searching the appropriate hash map bucket. 4. If the facet is new (not found in the bucket), expands the bucket by 4 slots if it's full or empty, then adds the facet to both the bucket and the return array. 5. If the facet was already seen, skips it to maintain uniqueness. 6. Finally, sets the correct length of the return array to match the number of unique facets found. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly for each selector. - Growing in fixed-size chunks (4 for buckets) keeps reallocations infrequent and prevents over-allocation, while keeping bucket sizes small for sparse key distributions. - Reusing the selectors array memory eliminates one memory allocation and reduces total memory usage, which saves gas. - This design is optimized for diamonds with many selectors across many facets, where the original O(n²) nested loop approach becomes prohibitively expensive. - The 256-bucket hash map trades a small fixed memory cost for dramatic algorithmic improvement in worst-case scenarios. - - -{`function facetAddresses() external view returns (address[] memory allFacets);`} - - -**Returns:** - - - ---- -### facets - -Gets all facets and their selectors. Returns each unique facet address currently used by the diamond and the list of function selectors that the diamond maps to that facet. How it works:** 1. Uses a memory-based hash map to group facets by the last byte of their address, reducing linear search costs from O(n²) to approximately O(n) for most cases. 2. Reuses the selectors array memory space to store pointers to Facet structs, avoiding an extra memory allocation for the intermediate array. 3. For each selector, looks up its facet address and checks if we've seen this facet before by searching the appropriate hash map bucket. 4. If the facet is new, expands the bucket by 4 slots if it's full or empty, creates a Facet struct with a 16-slot selector array, and stores a pointer to it in both the bucket and the facet pointers array. 5. If the facet exists, expands its selector array by 16 slots if full, then appends the selector to the array. 6. Finally, copies all Facet structs from their pointers into a properly-sized return array. Why this approach:** - Hash mapping by last address byte provides O(1) average-case bucket lookup instead of scanning all previously-found facets linearly. - Growing in fixed-size chunks (4 for buckets, 16 for selector arrays) keeps reallocations infrequent and prevents over-allocation. - Reusing the selectors array memory reduces total memory usage and allocation. - This design is optimized for diamonds with many facets and many selectors, where the original O(n²) nested loop approach becomes prohibitively expensive. - - -{`function facets() external view returns (Facet[] memory facetsAndSelectors);`} - - -**Returns:** - - - - - - -## Best Practices - - -- Ensure this facet is added to the diamond during initialization. -- Call facet inspection functions through the diamond proxy address. -- Verify storage compatibility before upgrading facets to maintain introspection integrity. - - -## Security Considerations - - -Follow standard Solidity security practices.

- - - - - - -## Best Practices - - -- Call `safeTransferFrom` or `safeBatchTransferFrom` for standard ERC-1155 transfers to ensure receiver contract compatibility. -- Use `mint` and `burn` functions for internal token lifecycle management. -- Ensure correct `_operator` is passed for transfers to maintain accurate approval tracking. - - -## Integration Notes - - -This module utilizes the diamond storage pattern, storing ERC-1155 state within a dedicated slot identified by `keccak256(\"compose.erc1155\")`. The `ERC1155Storage` struct, containing `uri` and `baseURI` fields, is managed at this position. Functions like `mint`, `burn`, and transfers directly interact with this shared storage, ensuring all facets accessing this storage see consistent token balances and URI information. - - -

It manages a `RoyaltyStorage` struct containing `defaultRoyaltyInfo`. Functions like `setDefaultRoyalty` and `setTokenRoyalty` directly modify this shared storage. The `royaltyInfo` function reads from this storage to provide royalty details, falling back to default settings when token-specific settings are absent. All modifications are immediately visible to other facets accessing the same diamond storage. - - -

Otherwise, describe behavior as "ERC-20-like" / "ERC-721-like" instead of claiming full compliance. +- Diamond and storage semantics: + - Treat "diamond", "facet", and "module" as in ERC-2535: a diamond is the primary contract address; facets are logic contracts reached through `delegatecall`; modules are internal libraries that operate on shared diamond storage. + - Always keep in mind that multiple facets share the same storage via the diamond storage pattern; explain how a module or facet reads/writes this shared state using the provided `storageContext`. +- Tone and style: Active voice, concise sentences, zero fluff/marketing.

It reads and modifies the `FacetList` within the `DiamondStorage` struct. Changes made through this module's upgrade functions are immediately visible to all facets accessing the same diamond storage. The optional `delegatecall` in `upgradeDiamond` allows for complex state interactions or initializations that are critical for maintaining invariants across the diamond. + + +

Changes made via this module are immediately visible to any facet accessing the same storage slot via the diamond proxy. +This module utilizes the diamond storage pattern, accessing royalty information from a dedicated storage slot identified by `keccak256("erc2981")`. The `RoyaltyStorage` struct, containing `defaultRoyaltyInfo`, is read and written through this slot. Functions like `setDefaultRoyalty`, `setTokenRoyalty`, `resetTokenRoyalty`, and `deleteDefaultRoyalty` directly modify this shared storage. The `royaltyInfo` function queries this storage to provide the appropriate royalty details for a given token, falling back to the default if no token-specific entry exists. Any facet with access to the diamond's storage can read these values immediately after they are updated.
