Crossbeam Channel

Build Status License Cargo Documentation Rust 1.28+ chat

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:

  • Senders and Receivers 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:

[dependencies]
crossbeam-channel = "0.4"

Next, add this to your crate:

#[macro_use]
extern crate crossbeam_channel;

Compatibility

The minimum supported Rust version is 1.28. Any change to this is considered a breaking change.
