A lightweight WebAssembly runtime that is fast, secure, and standards-compliant
wit-parser
Counted from the Cargo.toml manifests of the 28 indexed repositories that declare wit-parser as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in wit-parser 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 wit-parser projects that also use it.
