Crossbeam Channel

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.

Usage

Add this to your Cargo.toml:

toml [dependencies] crossbeam-channel = "0.4"

Next, add this to your crate:

```rust

[macro_use]

extern crate crossbeam_channel; ```
