The port is still a work in progress. At some point it will make more sense to develop in feature branches and push to main via feature PRs rather than just doing all development directly on this rust branch.

The conditions for merging are those necessary for that workflow to be sensible; concretely:

  • 1. The Rust crate compiles successfully
  • 2. The Python test suite has been updated so that all tests reflect the intended API post-rewrite and can represent a target that feature PRs can look to address
  • 3. CI/CD has been put in place
  • 4. The README has been updated to reflect the current development status
  • 5. Issues have been created for all remaining points on my To-Do list
