Research direction
Read the stabilization section of the Rust std-dev guide linked in the issue, then review the tracking issue and implementation PR #165546. The issue says OsStr::split_at_unchecked depends on #156199; check that dependency and the stabilization criteria before assessing readiness. Done means the stabilization PR is prepared for the listed APIs once the dependency is satisfied.
Written by the indexing model from the issue text.
Description
Feature gate: #![feature(str_split_at_unchecked)]
This is a tracking issue for exposing the split_at_unchecked and split_at_mut_unchecked on str and OsStr.
Public API
impl str {
pub const unsafe fn split_at_unchecked(&self, mid: usize) -> (&str, &str);
pub const unsafe fn split_at_mut_unchecked(&mut self, mid: usize) -> (&mut str, &mut str);
}
impl OsStr {
pub unsafe fn split_at_unchecked(&self, mid: usize) -> (&OsStr, &OsStr);
}
Remarks
OsStr::split_at_unchecked needs to stabilize after #156199.
