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 r? rust-lang/libs-api @rustbot label +T-libs-api -T-libs to request review from a libs-api team reviewer. 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

Other than bumping the version to 1.63, LGTM.

Sorry to bump this again, but I think this stabilization is super exciting and important, since it finally allows for const offsetof(Foo.bar) calculations. I think by this point it should be stable since = "1.65.0" since 1.63 has been released, but could someone from the libs-api team (@jhpratt?) take a look at it after? The FCP was completed 5+ months ago at this point.

jhpratt · 2022-08-24T18:35:25Z

I'm not on T-libs-api, but I'll take another look at it in the near future.

jhpratt

As with before, diff LGTM. Just needs the version bumped to 1.65, naturally.
