Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @nrc (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

Pulling it out to deal with the tidy fixes.

@chamoysvoice - you can run tidy and fix the errors using:

python src/bootstrap/bootstrap.py --stage 1 --step check-tidy

It's like running the test suite, but checks against code following the style guidelines.
