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 Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed.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

Thanks for the PR, team! A couple of notes on contribution style:

• In a PR that's directly related to an issue, make sure to link to that issue in the PR! Paste a link like so https://github.com/tessel/project/issues/345 in a comment; Github will create cross-linking so visitors to the issue see that it's being addressed
• If your commit message is "fixes (issue link)", Github will automatically close that issue when your PR is accepted! This is encouraged
• You have three different commits for this PR, but their commit messages are essentially the same. Any time you make a commit, your commit message should show why this commit in particular was needed– even if it's "adding (thing) that I forgot in previous commit". Can you please either amend the commits, or squash them? ("amend" and "squash" are both git commands, and your coaches should be able to help, as this is challenging for most people the first several times)

Just one note on the commit itself: you need a space between "*" and the list item, or it won't be a bulleted list in Markdown.
