      [arguments] <modules>: Move prefix from pyproject to cargo.
      <test-flags>: Run tests for installed module.
      [phases]{build-python-module, install-python-module,
      add-install-to-pythonpath, check-python-module}: Remove phases.
      {prepare-cargo-build-system}: New phases.
      [native-inputs]: Remove python-wrapper; add rust, and rust:cargo; add
