cargo-llvm-cov

[EXPERIMENTAL] A wrapper for source based code coverage (-Zinstrument-coverage).

Installation

cargo install cargo-llvm-cov

cargo install cargo-binutils

cargo install rustfilt

rustup component add llvm-tools-preview

Alternatively, download compiled binaries from GitHub Releases.

cargo-llvm-cov relies on unstable compiler flags so it requires a nightly toolchain to be installed, though does not require nightly to be the default toolchain or the one with which cargo-llvm-cov itself is executed. If the default toolchain is one other than nightly, running cargo llvm-cov will find and use nightly anyway.

Usage

See cargo llvm-cov --help for a complete list of options

By default, only the summary is displayed in the terminal.

cargo llvm-cov --html
open target/llvm-cov/index.html

or

cargo llvm-cov --html --open

With json report:

cargo llvm-cov --json
