## Crate of the Week
This week's crate is [rust-sel4](https://github.com/seL4/rust-sel4/), a no\_std crate to bind to the Se4L microkernel APIs.
Thanks to [Robbie VanVossen](https://users.rust-lang.org/t/crate-of-the-week/2704/1432) for the suggestion!
[Please submit your suggestions and votes for next week][submit_crate]!

## Calls for Testing
An important step for RFC implementation is for people to experiment with the
implementation and give feedback, especially before stabilization.
If you are a feature implementer and would like your RFC to appear in this list, add a
`call-for-testing` label to your RFC along with a comment providing testing instructions and/or
guidance on which aspect(s) of the feature need testing.
##### [Rust](https://github.com/rust-lang/rust/issues?q=is%3Aopen+label%3Afinal-comment-period+sort%3Aupdated-desc)
* *No calls for testing were issued this week by [Rust](https://github.com/rust-lang/rust/labels/call-for-testing),
[Rust language RFCs](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing) or
[Rustup](https://github.com/rust-lang/rustup/labels/call-for-testing).*
[Let us know](https://github.com/rust-lang/this-week-in-rust/issues) if you would like your feature to be tracked as a part of this list.

### Rust Compiler Performance Triage
Strange week with lots of noise peeking through the performance runs. The only really significant change was a performance improvement that comes from allowing out of order encoding of the dep graph.
Triage done by **@rylev**.
