## Crate of the Week

<!-- COTW goes here -->

[Please submit your suggestions and votes for next week][submit_crate]!

[submit_crate]: https://users.rust-lang.org/t/crate-of-the-week/2704

## 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.

<!-- If there are new CfT items this week, include:

[Repo Name](Repo URL)
* [<Feature name>](<Feature URL>)
* [Testing steps](<Testing Steps URL>)

- and make note in the item so the authors know to remove the `call-for-testing` label:
This RFC will appear in the **Call for Testing** section of the next issue (#) of This Week in Rust (TWiR).
You may remove the `call-for-testing` label. Please feel free to leave the `call-for-testing` label in place if you would like this RFC to appear again in another issue of TWiR.

- where `Repo Name` and `Repo URL` are one of:
[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)

- and `Testing steps` points directly to the procedures the item wants users to exercise.

- For all `Repo Names` with no new CfT items this week: use (removing the repos for which new
CfT items did appear, of course)

* *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)

If you are a feature implementer and would like your RFC to appear on the above list, add the new `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.
