//! For now, this module is limited to extracting file descriptors,
//! but its functionality will grow over time.
//! 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.
