A modern runtime for JavaScript and TypeScript.
num-integer
Counted from the Cargo.toml manifests of the 96 indexed repositories that declare num-integer as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in num-integer 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 num-integer projects that also use it.
