(Maybe it already warns for yanked crates? Not if it doesn't touch the network.) - Should anyone be able to add I-libs-api-nominated? - Yes. - [[95290](https://github.com/rust-lang/rust/pull/95290)] *Document that \`OsString\` and \`OsStr\` are bytes; provide conversions to bytes* - skipped. ### Waiting on team - [1 `rust-lang/rust` `T-libs-api` `S-waiting-on-team` items](https://github.com/rust-lang/rust/issues?q=label:T-libs-api+label:S-waiting-on-team+is:open) - [[87074](https://github.com/rust-lang/rust/issues/87074)] *Tracking Issue for RFC 3128: I/O Safety* - skip ### Needs decision None ### Stalled Tracking Issues - [304 `rust-lang/rust` `T-libs-api` `C-tracking-issue` items](https://github.com/rust-lang/rust/issues?q=label:T-libs-api+label:C-tracking-issue+is:open+sort:updated-asc) - [[49355](https://github.com/rust-lang/rust/issues/49355)] *Tracking issue for implementing stack probe correctly* - tracking issue seems like it should be a label - close issue, add label, tag mentioned issues with label - [[75638](https://github.com/rust-lang/rust/issues/75638)] *Tracking Issue for Iterator::join* - tracking issue for a PR that got closed, close the issue too - [[67521](https://github.com/rust-lang/rust/issues/67521)] *Tracking issue for const \`alloc::Layout\`* - mostly stabilized, need to update tracking issue - [[61415](https://github.com/rust-lang/rust/issues/61415)] *Use const generics for array impls* - blocked by zero length array default issue, need to figure out a way to resolve that overlap issue - [[72505](https://github.com/rust-lang/rust/issues/72505)] *Tracking issue for \`#!\[feature(const\_float\_classify)\]\`* - Blocked on float computations being able to guarantee identical values whether computed at compile time or runtime - https://github.com/rust-lang/rust/issues/41758 : resize_with was landed, do not want resize_default, close issue - https://github.com/rust-lang/rust/issues/67057 : should be perma-unstable - https://github.com/rust-lang/rust/issues/82725 : PR never landed because of perf issues. Should close the issue and leave a comment letting ppl know if they want to revisit it they should file a PR, work through the issues, then file a tracking issue, in that order ## Actions - [ ] Reply to all issues/PRs discussed in this meeting, or add them to the [open action items](https://hackmd.io/ovrbJj6CRduRgSA0Wzg2zg). _Generated by [fully-automatic-rust-libs-team-triage-meeting-agenda-generator](https://github.com/rust-lang/libs-team/tree/main/tools/agenda-generator)_
