Crate of the Week

This week's crate is office2pdf, a standalone library or binary to generate PDF from OOXML (docx, xlsx, etc.) files.

Thanks to One for the suggestion!

Please submit your suggestions and votes for next week!

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 byRust, Cargo, Rustup or Rust language RFCs.

Let us know if you would like your feature to be tracked as a part of this list.

Quote of the Week

After all, Rust only became as good as it is by going through a rather drastic transformation. At one point it had a GC and Green Threads, famously. There's no substitute for making it exist and seeing how it does on a real problem.

– scottmcm on rust-users

Thanks to Jonas Fassbender for the suggestion!
