rayon
Data parallelism for Rust — parallel iterators over thread pools.
rayon provides parallel iterators that distribute work across a work-stealing thread pool. Any sequential iterator chain can be parallelized by replacing .iter() with .par_iter(). Thread management, load balancing, and synchronization are automatic.
Used in CPU-bound code that processes large collections — image processing, data analysis, search indexing, build systems, and numerical computing. par_iter() is the one-line path from sequential to parallel processing in Rust.
Counted from the Cargo.toml manifests of the 961 indexed repositories that declare rayon as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in rayon projects. The most distinctive pairings rank first — crates these projects use far more than the average indexed Rust project does, not just crates that are popular everywhere. Each percentage is the share of rayon projects that also use it.
