Crossbeam provides lock-free data structures and utilities for concurrent programming. The crossbeam-channel crate offers multi-producer multi-consumer channels with better performance than std::sync::mpsc. crossbeam-utils has scoped threads (borrow data without 'static). crossbeam-epoch enables lock-free memory reclamation. I use crossbeam when the standard library's concurrency primitives aren't enough: MPMC channels, work stealing, or lock-free algorithms. The scoped threads are especially handy for parallelizing work that borrows local data. Crossbeam is battle-tested and used in high-performance systems. It's the next step after mastering std::sync.
