//! Lightweight but safe abstractions around Linux system calls related to
//! file descriptors.
//!
//! This goal of this crate is to expose a convenient API while skipping any
//! unnecessary abstraction. In most cases calls to functions in this crate
//! should reduce to inline system calls and some minimal argument and result
//! conversion code, and the results should be generally unsurprising to anyone
//! who is familiar with the underlying system call behavior.
//!
//! The functions in this crate wrap functions in crate [`linux_unsafe`] to
//! actually make the system calls, and so the platform support for this
//! crate is limited to what that other crate supports.
//!
//! Implements standard library I/O traits by default, but can be made friendly
//! to `no_std` environments by disabling the default feature `std`.
//!
//! The initial versions of this crate are focused only on basic file
//! operations, until the API for that feels settled. In later releases the
//! scope will hopefully increase to cover most or all of the system calls
//! that work with file descriptors.
