history
Project history and usage
cargo-llvm-cov is a Cargo subcommand for LLVM source-based coverage in Rust projects. Its README says it wraps rustc -C instrument-coverage and supports cargo test, cargo run, and cargo nextest flows.
Project history
The crate was first published on crates.io in January 2021 as version 0.0.0. Its official README emphasizes precise line, region, and optional branch coverage while avoiding extra layers between rustc, cargo, and llvm-tools.
Adoption history
The tool became part of common Rust CI coverage workflows because it can emit text, HTML, JSON, lcov, Cobertura, and Codecov-compatible reports. It is packaged by Homebrew, Nix, and Arch according to the input package-manager facts; crates.io reported 6,323,980 downloads when checked on 2026-06-30.
How it is used
Typical usage is cargo llvm-cov for test coverage, cargo llvm-cov --html or --open for local reports, cargo llvm-cov --lcov for CI uploads, and cargo llvm-cov nextest when running tests through cargo-nextest.
Why package nerds care
It matters to Rust package maintainers because it standardizes coverage collection around the compiler's LLVM instrumentation rather than a separate test harness, making coverage easier to reproduce locally and in package CI.
Timeline
- 2021: First crates.io release 0.0.0.
