Add #[must_use] to remaining std functions (O-Z) I've run out of compelling reasons to group functions together across crates so I'm just going to go module-by-module. This is half of the remaining items from the `std` crate, from O-Z. `panicking::take_hook` has a side effect: it unregisters the current panic hook, returning it. I almost ignored it, but the documentation example shows `let _ = panic::take_hook();`, so following suit I went ahead and added a `#[must_use]`. ```rust std::panicking fn take_hook() -> Box<dyn Fn(&PanicInfo<'_>) + 'static + Sync + Send>; ``` I added these functions that clippy did not flag: ```rust std::path::Path fn starts_with<P: AsRef<Path>>(&self, base: P) -> bool; std::path::Path fn ends_with<P: AsRef<Path>>(&self, child: P) -> bool; std::path::Path fn with_file_name<S: AsRef<OsStr>>(&self, file_name: S) -> PathBuf; std::path::Path fn with_extension<S: AsRef<OsStr>>(&self, extension: S) -> PathBuf; ``` Parent issue: #89692 r? `@joshtriplett` |
