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 = "0.5"

Compatibility

Crossbeam Channel supports stable Rust releases going back at least six months, and every time the minimum supported Rust version is increased, a new minor version is released. Currently, the minimum supported Rust version is 1.38.
