Installation

Install cargo-mutants from source:

You can also use cargo binstall from cargo-binstall, or install binaries from GitHub releases.

After installing cargo-mutants, you should be able to use it to run tests under any toolchain, even toolchains that are far too old to build cargo-mutants, using the standard + option to cargo:
