# Crate of the Week
This week's Crate of the Week is [crossbeam](https://crates.io/crates/crossbeam). This is a library of non-blocking data structures and synchronization primitives that makes writing concurrent programs easier and more efficient (both in terms of code and runtime).
Thanks to [DroidLogician](https://users.rust-lang.org/users/droidlogician) for the suggestion.
[Submit your suggestions for next week][submit_crate]!
