Borrow Vec<T, A> as [T] #99317

Hello all,

When Vec was parametrized with A, the Borrow impls were omitted and currently Vec<T, A> can't be borrowed as [T]. This PR fixes that.

This was probably missed, because the Borrow impls are in a different file - src/alloc/slice.rs.

We briefly discussed this here: rust-lang/wg-allocators#96 and I was told to go ahead and make a PR :)

I tested this by building the toolchain and building my code that needed the Borrow impl against it, but let me know if I should add any tests to this PR.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

This seems okay to me, and I think isn't a stable API change (since Allocator is an unstable trait), so going to go ahead and r+ directly.
