//! A unix domain sockets crate that supports abstract addresses, fd-passing and SOCK_SEQPACKET sockets.
//!
//! File-descriptor passing and abstract socket support for stream and datagram sockets is provided
//! via extension traits for existing types in `std::os::unix::net` and (opt-in) `mio_uds`.
