1//! Asynchronous channels.
2//!
3//! Like threads, concurrent tasks sometimes need to communicate with each
4//! other. This module contains two basic abstractions for doing so:
5//!
6//! - [oneshot], a way of sending a single value from one task to another.
7//! - [mpsc], a multi-producer, single-consumer channel for sending values
8//! between tasks, analogous to the similarly-named structure in the standard
9//! library.
10//!
11//! All items are only available when the `std` or `alloc` feature of this
12//! library is activated, and it is activated by default.
