Tracking Issue for extra deref methods

[clarfonthey]

Feature gate: #![feature(deref_mut_methods)]

This is a tracking issue for missing named methods which are equivalent to a DerefMut implementation. It is loosely related to #144288, which tracks methods which already exist but are not const-stable.

Public API

impl OsString {
    pub const fn as_mut_os_str(&mut self) -> &mut OsStr;
}
impl PathBuf {
    pub const fn as_mut_path(&mut self) -> &mut Path;
}
