A markup-based typesetting system that is powerful and easy to learn.
ryu
Counted from the Cargo.toml manifests of the 59 indexed repositories that declare ryu as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in ryu 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 ryu projects that also use it.
