+//! 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(())
+//! }
+//! ```
+//!
+//! [`OsStr`]: crate::ffi::OsStr
+//! [`OsString`]: crate::ffi::OsString
