+//! Future-aware synchronization
+//!
+//! This module is enabled with the **`sync`** feature flag.
+//!
+//! Tasks sometimes need to communicate with each other. This module contains
+//! two basic abstractions for doing so:
+//!
+//! - [oneshot](oneshot/index.html), a way of sending a single value
+//!   from one task to another.
+//! - [mpsc](mpsc/index.html), a multi-producer, single-consumer channel for
+//!   sending values between tasks.
+//! - [lock](lock/index.html), an asynchronous `Mutex`-like type.
+//! - [watch](watch/index.html), a single-producer, multi-consumer channel that
+//!   only stores the **most recently** sent value.
