| |
| This crate provides multi-producer multi-consumer channels for message passing. |
| It is an alternative to [`std::sync::mpsc`] with more features and better performance. |
| |
| Some highlights: |
| |
| * [`Sender`]s and [`Receiver`]s can be cloned and shared among threads. |
| * Two main kinds of channels are [`bounded`] and [`unbounded`]. |
| * Convenient extra channels like [`after`], [`never`], and [`tick`]. |
| * The [`select!`] macro can block on multiple channel operations. |
| * [`Select`] can select over a dynamically built list of channel operations. |
| * Channels use locks very sparingly for maximum [performance](benchmarks). |
