Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @huonw (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. The way Github handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed.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.

Hi, quick question for the future. Is it considered best practice to add new commits to pending pull requests or create new pull request ? :)

Thanks! For small things like this feel free to tack them onto existing PRs, but more substantial changes should likely make their way into a new PR.
