### FCPs

<a href="https://github.com/rust-lang/rust/issues?q=is%3Aopen+label%3AT-libs-api+label%3Aproposed-final-comment-period">3 <code>rust-lang/rust</code> FCPs</a>

- [[merge 85766](https://github.com/rust-lang/rust/issues/85766#issuecomment-849994105)] *Stabilize File::options()* - (2 checkboxes left)
- [[merge 44434](https://github.com/rust-lang/rust/issues/44434#issuecomment-865374685)] *Provide an API to extract fields from Command builder* - (3 checkboxes left)
- Several of us feel slightly concerned. We should file a concern.
- [[merge 80690](https://github.com/rust-lang/rust/issues/80690#issuecomment-846481791)] *Tracking Issue for BufWriter::into\_raw\_parts* - (1 checkboxes left)

### Nominated

- [6 `rust-lang/rust` `T-libs-api` `I-nominated` items](https://github.com/rust-lang/rust/issues?q=is:open+label:T-libs-api+label:I-nominated)
- [[81050](https://github.com/rust-lang/rust/pull/81050)] *Stabilize core::task::ready!*
FCP finished. Should be merged?
- [[83791](https://github.com/rust-lang/rust/pull/83791)] *Weaken guarantee around advancing underlying iterators in zip*
- [[87173](https://github.com/rust-lang/rust/pull/87173)] *unstable proc\_macro tracked::\* rename/restructure*
- [[87264](https://github.com/rust-lang/rust/pull/87264)] *proc\_macro: Add an expand\_literal method to TokenStream*
- Work towards 'expand_stream'. Keep it unstable until we make a decision how we want to do that.
- Suggestion: rename it and return a TokenStream, but have the first implementation only work for expanding into a literal (as it is right now). Then explore more flexibility later.
- [[87408](https://github.com/rust-lang/rust/pull/87408)] *Hide allocator details from TryReserveError*
