I'm extremely excited about posts/libraries like these. They really show off the unique powers of Rust in a way that's a bit more compelling than "Rust is just C++14 with a bit stronger guarantees and more clean semantics."
Also worth noting, and something I missed when I read the draft of this post: this isn't just an implementation of a lock-free structure: it's a whole library, Crossbeam[1] that helps you implement your own lock-free structures.
