## Crate of the Week
This week's crate is [index\_permute](https://crates.io/crates/index_permute), a library for in-place clone-less permutation on mutable slices.
Despite a lack of suggestions this week, llogiq is fairly pleased with his choice.
[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.
* *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),
[Cargo](https://github.com/rust-lang/cargo/labels/call-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.
### [RFCs](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing)
### [Rust](https://github.com/rust-lang/rust/labels/call-for-testing)
### [Rustup](https://github.com/rust-lang/rustup/labels/call-for-testing)

### Rust Compiler Performance Triage
Fairly busy week with improvements outweighing regressions. Most of the regressions were considered acceptable given the circumstances (such as landing a long awaited feature). By far the biggest win comes from being a bit smarter about hashing certain information inside of `DefPathHash`. Since hashing happens quite a lot in th compiler's query system, optimizing when hashing happens can have large performance impacts.
Triage done by **@rylev**.

# Quote of the Week
> In a way, \[the\] borrow checker also makes interfaces simpler. The rules may be restrictive, but the same rules apply to everything everywhere. I can learn them once, and then know what to expect from every API using references. There are no exceptions in libraries that try to be clever. There are no exceptions for single-threaded programs. There are no exceptions for DLLs. There are no exceptions for programs built with -fpointers-go-sideways. It may be tricky like a game of chess, but I only need to consider the rules of the game, and not odd stuff like whether my opponent glued pieces to the chessboard.
