+//! TCP bindings for `tokio`.
+//!
+//! This module contains the TCP networking types, similar to the standard
+//! library, which can be used to implement networking protocols.
+//!
+//! Connecting to an address, via TCP, can be done using [`TcpStream`]'s
+//! [`connect`] method, which returns [`ConnectFuture`]. `ConnectFuture`
+//! implements a future which returns a `TcpStream`.
+//!
+//! To listen on an address [`TcpListener`] can be used. `TcpListener`'s
+//! [`incoming`][incoming_method] method can be used to accept new connections.
+//! It return the [`Incoming`] struct, which implements a stream which returns
+//! `TcpStream`s.
+//!
