+//! A socket address for any kind of socket.
+//!
+//! This is similar to [`std::net::SocketAddr`], but also supports Unix-domain
+//! socket addresses.
+//!
+//! # Safety
+//!
+//! The `read` and `write` functions allow decoding and encoding from and to
+//! OS-specific socket address representations in memory.
