//! # xsk-rs
//!
//! A rust interface for AF_XDP sockets using libbpf.
//!
//! For more information please see the [networking
//! docs](https://www.kernel.org/doc/html/latest/networking/af_xdp.html)
//! or a more [detailed
//! overview](http://vger.kernel.org/lpc_net2018_talks/lpc18_paper_af_xdp_perf-v2.pdf).
//!
//! Some simple examples may be found in the `examples` directory in
//! the GitHub repo.
