1//! Platform-specific extensions to `std` for Unix platforms.
2//!
3//! Provides access to platform-level information on Unix platforms, and
4//! exposes Unix-specific functions that would otherwise be inappropriate as
5//! part of the core `std` library.
6//!
7//! It exposes more ways to deal with platform-specific strings ([`OsStr`],
8//! [`OsString`]), allows to set permissions more granularly, extract low-level
9//! file descriptors from files and sockets, and has platform-specific helpers
10//! for spawning processes.
11//!
12//! # Examples
13//!
14//! ```no_run
15//! use std::fs::File;
16//! use std::os::unix::prelude::*;
17//!
18//! fn main() -> std::io::Result<()> {
19//! let f = File::create("foo.txt")?;
20//! let fd = f.as_raw_fd();
21//!
22//! // use fd with native unix bindings
23//!
24//! Ok(())
25//! }
26//! ```
27//!
28//! [`OsStr`]: crate::ffi::OsStr
29//! [`OsString`]: crate::ffi::OsString
