Purpose: mutest-rs generates and evaluates Rust program mutations to assess a test suite.
Workflow: It runs through the `cargo mutest run` subcommand on Cargo packages and workspaces.
Test compatibility: The documentation says that if `cargo test` works for a package, `cargo mutest run` will generally run the same test suite under mutation analysis.
Mutation batching: An experimental batching technique combines mutations in distinct program areas to increase parallel evaluation of test cases.
Configuration: Users can control the active mutation operators with the `--mutation-operators` argument; its default is `all`.
Integration: The tool provides a Cargo-compatible interface and supports Cargo package and workspace targeting options.
Installation: The documented installation method is to compile the project from source; the site says compiling it yourself is currently the only option.
Build requirement: The installation guide instructs users to build the `mutest-runtime` crate and install `mutest-driver` and `cargo-mutest` locally.
Safety: The documentation describes a safety property for mutations based on the safety of the scope where they are introduced and the safety flag used to invoke the tool.
Research status: The project README describes mutest-rs as primarily a research tool originally developed for the maker’s ongoing PhD work.
License: The project README states that mutest-rs is dual licensed under Apache 2.0 and MIT terms.
