#rustinparis — Public Fediverse posts

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: https://www.meetup.com/rust-paris/events/314283634

Enjoy!

#rust #rustinparis

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!

"Maintenance is not just code. We are a community of contributors, not a code repository." Oli says.

#RustLang #RustInParis

Oli @oli closes the day with "Maintaining Rust".

#RustInParis #RustLang

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.
#RustInParis #RustLang

Nadri is showing the #RustInParis goodie: the Rust in Paris cap.

Jana @jana Dönszelmann is now presenting "It's the people that matter"
#RustLang #RustInParis

Bertrand Darbon is now presenting "One bus to message them all: async rust for modular monoliths"

#RustLang #RustInParis

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.
#RustLang #RustInParis

Christoph Lürig is presenting "AAA Multiplayer Patterns Meet Rust, Tokio and WebAssembly". #RustLang #RustInParis

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.

#RustLang #RustInParis

Simon @simon Sapin is talking about "Building CPU from scratch with NAND gates"
#RustLang #RustInParis

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.
#RustLang #RustInParis

Next was Alejandra @blyxyas Gonzales presenting "How I sliced the Clippy runtime in half"
#RustLang #RustInParis

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.
#RustLang #RustInParis

The second talk was by Guillaume @imperio Gomez on the Rust GCC backend.
#RustLang #RustInParis

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!

#RustLang #RustInParis

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
#RustLang #RustInParis

Rust In Paris started with Waffle @wffl presenting the Little Rust Delights. #RustLang #RustInParis

Rust In Paris starts soon !

#RustInParis #RustLang

See you at https://www.rustinparis.com today! My friends are giving talks :D

#programming #rust #rustinparis

Now on my way to @rustinparis!

Looking forward to good talks and meeting new people :)

Hit me up if you want to talk/connect or just have a chat!

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!

#rust #rustinparis

We (Amin Faez and @d_niehues) will be at @rustinparis on the 27th of March.

Looking forward to meeting new people. If you are interested in rust, cryptography or just wanna chat, hit us up!

#rust #paris #rustinparis #cryptography

@imperio Would love to be there for the Meetup on the 26th, but my train only arrives rather late.

Would be happy to have a chat and a drink after the conference on the 27th however.

Feel free to hit me up!
