3//! Future-aware synchronization
4//!
5//! This module is enabled with the **`sync`** feature flag.
6//!
7//! Tasks sometimes need to communicate with each other. This module contains
8//! basic abstractions for doing so:
9//!
10//! - [oneshot](oneshot/index.html), a way of sending a single value
11//!   from one task to another.
12//! - [mpsc](mpsc/index.html), a multi-producer, single-consumer channel for
13//!   sending values between tasks.
14//! - [`Mutex`](struct.Mutex.html), an asynchronous `Mutex`-like type.
15//! - [watch](watch/index.html), a single-producer, multi-consumer channel that
16//!   only stores the **most recently** sent value.
