Crate
libc
Raw FFI bindings to C standard library functions and types.
What it is
libc provides raw bindings to the C standard library and POSIX APIs for all supported Rust targets — Linux, macOS, Windows, FreeBSD, and others. It defines the C numeric types (c_int, size_t, off_t) and function signatures needed to call system-level APIs from Rust.
Why it is commonly used
Foundation for any crate that wraps system calls or C libraries. Higher-level crates like nix build on libc to provide safe Rust interfaces to POSIX. Also used directly in unsafe code that requires system-level control.

Counted from the Cargo.toml manifests of the 1.5k indexed repositories that declare libc as a dependency — not download counts. Dependency data last verified 2026-08-13.
Often used with
Crates that show up unusually often in libc 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 libc projects that also use it.
