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

Whilst I understand that this is merely reflecting the current implementation, by documenting this behaviour are we not committing to it being forever the case where currently the implementation is (theoretically) free to be changed?

Which is to say, doesn't this need libs-api sign off?

HashMap::insert explicitly states that the key is not modified, and since HashSet<T> just wraps HashMap<T, ()>, the same guarantee follows. (Which is not to say that we're already promising this, but it would be easy.)

FWIW, IndexSet::insert does promise this too.

@workingjubilee

What is not clear, however, is that we wish to retain HashMap as an implementation detail of HashSet, and while we are almost certainly going to have a conversation where we quickly agree that we wish to do this, it is extremely painful to have these discussions preempted, because what is "easy" is not always correct.

A more compelling reason to accept this PR is that this was discussed beforehand as fully intentional by the people working on the standard library in the past:

#26888 (comment)
#27894

I would appreciate it if we did not "document existing behavior" for a random API without reference to such history, especially as it both easy to find and also easy to find the contrary case: where the "existing behavior" was documented without such consideration in ways that now cause problems.

@stepancheg

ping from triage - can you post your status on this PR? There hasn't been an update in a few months. Thanks!

FYI: when a PR is ready for review, send a message containing
@rustbot ready to switch to S-waiting-on-review so the PR is in the reviewer's backlog.

This is consistent with the behavior of HashMap::insert which already documents this behavior for keys. Starting an FCP since this is technically a new stable guarantee.

Compatibility Notes
-------------------

- [Alter `Display` for `Ipv6Addr` for IPv4-compatible addresses](rust-lang/rust#112606)
- Cargo changed feature name validation check to a hard error. The warning was
  added in Rust 1.49. These extended characters aren't allowed on crates.io, so
  this should only impact users of other registries, or people who don't publish
  to a registry.

- Cargo changed feature name validation check to a hard error. The warning was

  this should only impact users of other registries, or people who don't publish
