| //! 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. |
