    //! Platform-specific extensions to `std` for Unix platforms.
    //!
    //! Provides access to platform-level information on Unix platforms, and
    //! exposes Unix-specific functions that would otherwise be inappropriate as
    //! part of the core `std` library.
    //!
    //! It exposes more ways to deal with platform-specific strings (`OsStr`,
    //! `OsString`), allows to set permissions more granularly, extract low-level
    //! file descriptors from files and sockets, and has platform-specific helpers
    //! for spawning processes.
    //!
    //! # Examples
    //!
    //! ```no_run
    //! use std::fs::File;
    //! use std::os::unix::prelude::*;
    //!
    //! fn main() -> std::io::Result<()> {
    //!     let f = File::create("foo.txt")?;
    //!     let fd = f.as_raw_fd();
    //!
    //!     // use fd with native unix bindings
    //!
    //!     Ok(())
    //! }
    //! ```
