  1. Next Paris Rust meetup will be organized with Devoxx on the 23rd of April. Organization is therefore different than usual so I strongly advise to take a look at the meetup page if you're interested: meetup.com/rust-paris/events/3

    Enjoy!

  3. That's it for me for #RustInParis! There were great talks, great people and nice discussions; it ends a bit early, but let's meet again next year!

  7. During the EII implementation, it needed a big attribute refactor in rustc. And the community stepped up and helped Jana and Mara on this project. Many were first time Compiler contributors, and some even became team members.
    Which is a big reason Jana resents LLM PRs on the Rust project: it robs the opportunity for community-building, and learning in general, she says.

  15. Arthur @krtab Carcano's "Rust, Unicode gotchas, and the eight different string types" is on stage. He learned to stop worriying and trust UTF-8.

  19. The final step, is of course to run code on top of the RISC-V CPU running in the Simulator in Rust. Thanks to Embedded Rust, it's easy to generate freestanding RISC-V code, Simon says. He showed a demo of a binary compiled and then run into qemu. Then he used his own nand-level simulator, which was much slower. At a few kHz, it is as fast as an ENIAC from 1945, Simon says.

  23. Performance is also a money problem. Any time saved in CI/CD, can save a lot of money just in CI cost, because it is run so often. But answering a question from the audience, Alejandra did not get any money from the many of thousands of euros saved by big projects after her clippy optimizations.

  27. Backend and front-end are simple words right? Is this about Web development? No, in compilers, the backend is the part which does the code generation.

  31. Rust allows let without assignment, so a variable can be assigned only once later (mutation is still disallowed). This can be used to escape blocks, or to make multiple assignements in blocks more readable. Waffle also showed a much cooler trick to prevent using Trait objects, but for that you'll have to watch the video!

  33. In Rust, a loop is infinite, so its type is ! aka the never type. If the loop {...} has a break, the type changes to the unit type (). And break can even take a value, and its type becomes the type of the loop

  40. New Rust in Paris speaker is Arthur Carcano! His talk is named "Rust, Unicode gotchas, and the eight different string types". If you ever wanted to know what's the difference between String and OsString, you should definitely watch this talk!

    See you on friday!
