lucascs@protonmail.com Lucas C.S. cargo-llvm-cov collects code coverage using LLVM's source-based instrumentation (-C instrument-coverage) rather than a line-counting approximation, so it reports region and branch coverage that matches what the compiler actually emitted. It produces lcov, JSON, HTML and Cobertura output for CI consumption. https://github.com/taiki-e/cargo-llvm-cov/issues taiki-e/cargo-llvm-cov
