Box is missing `try_new_uninit_slice_in`

[AljoschaMeyer]

Hi,

while Box has both try_new_uninit_slice and new_uninit_slice_in, it lacks try_new_uninit_slice_in to fallibly allocate a slice of uninitialized memory with a given allocator. Is this deliberate or an oversight? What could be a good workaround for implementing this oneself?

Apologies if this is not the appropriate repo for this sort of question/feature suggestion.

Cheers,
Aljoscha

This is an oversight, a PR to add it is welcome.

Would be happy to make a PR. Please tell me if a PR to the main branch of https://github.com/rust-lang/rust is not what to do here. Done! rust-lang/rust#127415

Random piece of feedback: https://std-dev-guide.rust-lang.org/about.html never tells the reader which repository, branches, directories, etc to interact with.

Here we go: rust-lang/rust#127415
