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).
