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 Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed.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

@rust-highfive rust-highfive added the S-waiting-on-review Status: Awaiting review from the assignee but also interested parties. label Jul 24, 2020

Is is safe for rollups, perf wise?

I'm not sure, I'd assume so?

Docs are not that convincing 😅:

Should not be sprinkled around carelessly, as it causes a little bit of overhead.

@kanru I can reproduce the failure on my local, you should rebase.
