## Crate of the Week
This week's crate is [WhenFS](https://github.com/lvkv/whenfs), a FUSE filesystem that misuses your google calendar as storage. And yes, your schedule will look as packed as mine once you store one or two files in there.
Despite yet another week fully devoid of suggestions nor votes, llogiq is reasonably pleased with his choice.
[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. The following
RFCs would benefit from user testing before moving forward:
### [RFCs](https://github.com/rust-lang/rfcs/issues?q=label%3Acall-for-testing)
* *No calls for testing were issued this week.*
### [Rust](https://github.com/rust-lang/rust/labels/call-for-testing)
* *No calls for testing were issued this week.*
### [Rustup](https://github.com/rust-lang/rustup/labels/call-for-testing)
* *No calls for testing were issued this week.*
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
This week saw several large improvements caused mostly by the [update to LLVM 19](https://github.com/rust-lang/rust/pull/127513). There were some regressions in several pull requests, but most of them were immediately fixed in a follow-up PR.
Triage done by **@kobzol**.
