## Crate of the Week

This week's crate is [structstruck](https://crates.io/crates/structstruck), a proc-macro crate for enabling nested struct/enum definitions.

Thanks to [Julius Michaelis](https://users.rust-lang.org/t/crate-of-the-week/2704/1433) for the self-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.

* *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.

### [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.

### Rust Compiler Performance Triage

A relatively noisy week due to addition of new benchmarks as part of our [2025
benchmark update], and a number of large regressions in a rollup landing late
in the week (and so not yet investigated).

[2025 benchmark update]: https://github.com/rust-lang/rustc-perf/issues/2024

Triage done by **@simulacrum**.
Revision range: [25cdf1f6..62c5f58f](https://perf.rust-lang.org/?start=25cdf1f67463c9365d8d83778c933ec7480e940b&end=62c5f58f57670ce65e7fec34f8c4ba00c27da2d9&absolute=false&stat=instructions%3Au)

2 Regressions, 2 Improvements, 6 Mixed; 3 of them in rollups
31 artifact comparisons made in total

[Full report here](https://github.com/rust-lang/rustc-perf/blob/master/triage/2025-05-04.md).

### [Approved RFCs](https://github.com/rust-lang/rfcs/commits/master)

Changes to Rust follow the Rust [RFC (request for comments) process](https://github.com/rust-lang/rfcs#rust-rfcs). These

# Quote of the Week

> Well, the answer is basically yes. Our firmware is all Rust. Every component of our autonomy stack is Rust. Our app is 50% in Rust. And, our visualization tools are in Rust. Our production tools are in rust. The production QC software, which we ship to China, is in rust. Our internal websites are in rust. It's rust all over. We’ve drank the Rust Kool-Aid. In fact, there is no Python installed on the robots. This is not to dis Python at all, but it’s just simply not there.
>
> We use Python for neural network training. But Python is boxed to that. Everything else is Rust. And, the advantage of using Rust exponentially builds up.
