I don't think it should exist if we don't also ship an exit() api that takes this type. Amanieu: It could be an extension trait on ExitStatus David: ExitStatus can have a method that returns a larger integer. compatible with other platforms just fine. Mara: Seems fine to have a .code64() or w/e Amanieu: Disagree. Nobody will call that unless they specifically expect a large exit code. David: How confident are we that *every* non-UEFI platform will use i32? Josh: Aliases that change meaning per platform are painful Mara: +1. prefer extension trait or new method. Josh: Prefer extension trait. The 8482: We already have that for unix. Josh: For windows too. Consensus: extension trait for uefi. Josh to reply. ### (nominated) rust.tf/75744 *Tracking issue for \`ControlFlow\` enum, for use with \`try\_fold\` and in \`Try\`* Just asking for input on new methods. Not a stablization or anything like that. Mara: Naming seems fine. Josh: do we have other `_value` names in std? Josh: This shouldn't have as many helper methods as Result/Option. Amanieu: ControlFlow doesn't need short names. Consensus: fine as is, as unstable. Mara replied. ### (nominated) rust.tf/rfc3672 *RFC for project goals* ### (waiting on team) rust.tf/119550 *Rename \`AsyncIterator\` back to \`Stream\`, introduce an AFIT\-based \`AsyncIterator\` trait* WG-async ### (waiting on team) rust.tf/124941 *Stabilize const \`{integer}::from\_str\_radix\` i.e. \`const\_int\_from\_str\`* In FCP ### (new change proposal) rust.tf/libs406 *Make \`proc\_macro\` available outside procedural macro generation* Waiting on author ### (new change proposal) rust.tf/libs410 *Change \`std::fs::remove\_dir\_all\` to be idempotent* The 8472: ACP is a breaking change. The 8472: alternative: https://github.com/rust-lang/rust/pull/127623/files Mara: I think accepting the ACP might be fine. Behaviour makes sense. But rejecting the ACP and accepting that PR is also fine to me. Amanieu: Let's merge the PR and close the ACP. Mara: +1 Josh: +1 Amanieu to reply ### (new change proposal) rust.tf/libs411 *ACP: add \`std::any::is\_same\_type::\<T, U\>() \-\> bool\`* Propose `.is::<T>()` instead. Amanieu to reply ### (new change proposal) rust.tf/libs412 *File lock API* ### (new change proposal) rust.tf/libs413 *ACP: add bitwise/bytewise methods to NonZero* ### (stalled change proposal) rust.tf/libs176 *\`Peek\` trait for peekable iterators* ### (stalled change proposal) rust.tf/libs271 *Unix Domain Sockets on Windows* ### (stalled change proposal) rust.tf/libs124 *Integrate \`Error\` trait with panic interfaces* ### (stalled change proposal) rust.tf/libs111 *Restructure ptr\_metadata to minimal support* ### (stalled change proposal) rust.tf/libs181 *\`Cow::map\_borrowed\`, \`Cow::map\_owned\`, and \`Cow::map\`* _Generated by [fully-automatic-rust-libs-team-triage-meeting-agenda-generator](https://github.com/rust-lang/libs-team/tree/main/tools/agenda-generator)_
