All benchmarks are done in Rust and can be invoked with `cargo bench`. Currently this has it's own "harness" that behaves like `./tools/benchmark.py` did. Because of this tests inside `cli/bench` are currently not run. This should be switched to the language provided harness once the `#[bench]` attribute has been stabilized.
