+//! Asynchronous channels.
+//!
+//! Like threads, concurrent tasks sometimes need to communicate with each
+//! other. This module contains two basic abstractions for doing so:
+//!
+//! - [oneshot], a way of sending a single value from one task to another.
+//! - [mpsc], a multi-producer, single-consumer channel for sending values
+//!   between tasks, analogous to the similarly-named structure in the standard
+//!   library.
+//!
+//! All items are only available when the `std` or `alloc` feature of this
+//! library is activated, and it is activated by default.
