Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @aturon (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 Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed.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 @liranringel! It looks like there's a number of submodule updates here as well, were those intentional? If not, perhaps they could be backed out? (I think some are submodule deletions as well)

Also, it looks like you may have run cargo update? Perhaps that could be deferred to a different PR? We tend to prefer minor incremental updates to the Cargo.lock if possible

Ah this branch is a mess. I'll delete it and submit a new PR.
