### 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)

[m-ou-se (3)](https://rfcbot.rs/fcp/m-ou-se), [Amanieu (1)](https://rfcbot.rs/fcp/Amanieu), [yaahc (1)](https://rfcbot.rs/fcp/yaahc), [joshtriplett (1)](https://rfcbot.rs/fcp/joshtriplett)

### 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*
