Upgrade iroh to 1.0.0-rc.0

[drewr]

Part of datum-cloud/network-services-operator#168. See also datum-cloud/iroh-gateway#11.

iroh released v1.0.0-rc.0 on May 11 2026. This issue tracks the changes needed in this repo. iroh-gateway should be updated first (datum-cloud/iroh-gateway#11); this work can proceed in parallel once the blocking crate compatibility check passes.

Dependency bumps

Cargo.toml (workspace)

Crate	Current	Target
iroh	0.97.0	1.0.0-rc.0
iroh-base	0.97.0	0.98.0
iroh-relay	0.97.0	0.98.0
iroh-metrics	0.38.3	verify latest
iroh-proxy-utils	0.1.0	verify latest compatible
iroh-services	0.12.0	verify latest compatible (align with iroh-gateway which uses 0.13)

lib/Cargo.toml

• iroh-blobs: 0.99.0 → verify latest

n0des-local/Cargo.toml

• iroh-n0des: 0.10 → verify latest
• irpc-iroh: 0.13 → verify latest

Breaking API changes to fix

Old	New	File
PathWatcher	Connection::paths() (snapshot) + Connection::path_events() → PathEventStream	lib/src/node.rs
Connection::to_info() → ConnectionInfo	Connection::weak_handle()	lib/src/node.rs
CertConfig::Reloading	AcmeConfig builder	lib/src/node.rs
Source type	removed	lib/src/node.rs, lib/src/auth.rs
Exhaustive enum/struct patterns	many types now #[non_exhaustive] — add _ => arms	all pattern-match sites

Lower-risk files that still need verification with cargo check:

• lib/src/auth.rs — EndpointId, iroh_proxy_utils::Authority
• lib/src/diagnostics.rs — iroh_services API surface
• lib/src/state.rs — EndpointId, Authority, Ticket
• cli/src/dns_dev.rs — iroh_base::EndpointId
• n0des-local/src/lib.rs — iroh::*, iroh_n0des::*

Pre-flight

Before bumping Cargo.toml, confirm that iroh-proxy-utils and iroh-services have published versions compatible with iroh 1.0.0-rc.0. If iroh-proxy-utils isn't available yet, the escape hatch is already scaffolded (commented out in Cargo.toml):

# [patch."https://github.com/n0-computer/iroh-proxy-utils"]
# iroh-proxy-utils = { path = "../iroh-proxy-utils" }

Checklist

• Verify iroh-proxy-utils, iroh-services, iroh-n0des, irpc-iroh have compatible releases
• Bump workspace Cargo.toml dependencies
• Bump lib/Cargo.toml (iroh-blobs) and n0des-local/Cargo.toml
• Align iroh-services to same version as iroh-gateway (currently 0.13)
• Fix PathWatcher usages in lib/src/node.rs
• Fix conn.to_info() → conn.weak_handle() in lib/src/node.rs
• Fix any #[non_exhaustive] pattern-match failures across the workspace
• cargo build --workspace && cargo clippy --workspace && cargo test --workspace clean
