Stjepan Glavina wrote a great blog post on #crossbeam, a concurrency library for #rust. It explains what exactly crossbeam is for, some of its inner workings, and the project's plans for the future (sounds like super useful stuff!). The blog post contains lots of references to the docs, and it's been a great read!
