To give more background on this:

· crossbeam is a building block used in Rayon, which is Rust's main data parallelism library, roughly similar to OpenMP.

· crossbeam channels are very fast. They're in the same league as golang, sometimes faster (depending how you measure of course).

· crossbeam is an order of magnitude faster than channels in the Rust's standard library, while being more powerful and simpler to use. This is an example where experimentation in a 3rd party crate paid off compared to the standard library where a basic implementation went to die.

· it integrates with Rust's borrow checker of course, so you can use complex multi-threaded constructs (e.g. share stack-allocated objects between threads) without fear of data races or use-after-free.

Note that there are plans to integrate crossbeam's channel implementation into the standard library. This won't change the public API but would at least vastly improve the implementation. A similar thing was done with changing the implementation of `HashMap` to be a wrapper around the `hashbrown` library.

Phantastic reading list [0] as well! Big thank you to the authors for curating it!

I hope Stjepan is doing well. It was a shame for the Rust community to lose his talents.

From a quick internet stalking, it looks like he got married a year ago so he's likely doing fine personally.

I too think the rust community lost a lot when he decided to leave.

I wish crossbeam channels added support for async/await

You could use async_channel [1] it provides async multi-producer multi-consumer.

I'm using flume channels but I'd love to use crossbeam in an async environment

Async/await channels need a completely different implementation. It doesn't really make a ton of sense for a single crate to support both sync/threaded channels and async channels.

Flume channels support both, but yeah those are very different implementations. I think that supporting it in crossbeam would be great too

This user is just reposting trending repositories for karma.
