Incredibly fast JavaScript runtime, bundler, test runner, and package manager – all in one
allocator-api2
Counted from the Cargo.toml manifests of the 26 indexed repositories that declare allocator-api2 as a dependency — not download counts. Dependency data last verified 2026-08-13.
Crates that show up unusually often in allocator-api2 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.
