What is crossbeam and when to use it

Crossbeam is a Rust library for high-performance concurrency, offering primitives like channels and work-stealing deques for efficient multi-threaded applications.

Crossbeam is a Rust library providing high-performance, lock-free synchronization primitives like crossbeam-channel, crossbeam-deque, and crossbeam-utils for concurrent programming. Use it when you need efficient multi-threaded data sharing, work-stealing queues, or message passing that outperforms standard library alternatives in parallel workloads.
