After five years, I'm stepping down as team lead and member of the #rustlang library teams. It's been a wonderful time and a pleasure seeing the teams grow and evolve in these years. 1/4

New rustdoc bugfixes/improvements: - Doc generation time improvement and also reduced generated search index size: github.com/rust-lang/ru... and github.com/rust-lang/ru... - Fix merged doctest compilation time display: github.com/rust-lang/ru... Enjoy!

The RFC 3631, adding support for `doc_cfg` and in particular `doc_auto_cfg` just got merged! \o/ Now remains some polishing and some more testing but hopefully stabilization isn't too far away. PR: github.com/rust-lang/ru...

New rustdoc improvements of the day: - Added new `tyalias@` intra-doc link disambiguator in github.com/rust-lang/ru... - Added missing toolbar on the "all items" page in github.com/rust-lang/ru... Enjoy!

Just released the `0.37.1` version of the Rust [`sysinfo`](crates.io/crates/sysinfo) crate. Small bugs fixed (never trust API docs T_T). Changelog is here: github.com/GuillaumeGom... Enjoy!

Next Paris rust meetup will be organized in collaboration with @eurorust.eu on the 8th of October. You can register here: www.meetup.com/rust-paris/e... See you there!

New ferris plushes (twins) just entered the family :)

Back from my RustConf china trip (it was nice, still need to catch up my missed sleep), so I can try to catch up some rustdoc updates! We improved the lint about bare URLs surrounded by brackets in github.com/rust-lang/ru... We fixed the literal search on paths in github.com/rust-lang/ru... Enjoy!

I’m glad I got the opportunity to do amazing work on Rust over the last 3 years. It’s hard to quantify, but I hope people saw a difference due to my work on async traits/closures, the type system, diagnostics, style team, ICE fixes, internal refactors, speedups, edition 2024 etc.

I urge companies to take funding contributors seriously, in ways that aren’t tied to projects and goals. Being a generalist in the compiler meant that often I wasn’t working towards a roadmap, but my contributions *always* paid off in the long term extensibility of the language.

Following the rustdoc search rework (github.com/rust-lang/ru...), a lot of follow-ups improving various things like performance and size of downloaded data were done: github.com/rust-lang/ru... github.com/rust-lang/ru... github.com/rust-lang/ru... 1/2

Happy new Rust! 🎆🦀 Rust 1.89.0 has been released! This release brings you inferrred array length, new lints, u128/i128 in extern "C", NonZero<char>, File::lock, many x86 intrinsics, and much more! ✨ Check out the blog post and release notes for all the details: blog.rust-lang.org/2025/08/07/R...

Fixed a rustdoc "scrape examples" bug which crashed in some very specific cases. It was blocking bevy release, now that's one less issue for them. =D github.com/rust-lang/ru...

Rust in Paris 2025 talk videos are finally here! First talk is from Arthur!

The rustdoc team finally has a team charter! \o/ The goal was to actually describe how the team works and also make it easier for potential new contributors to know what the processes are. Hopefully, we succeeded. :) PR: github.com/rust-lang/ru...

With the Rust 2024 edition came the merged doctests feature (more info here: blog.guillaume-gomez.fr/articles/202...). I just added some extra information when you run them to know exactly where the time was spent when you run them in github.com/rust-lang/ru.... Enjoy!

I just joined the Rust compiler team! 🎉 github.com/rust-lang/te...

I just successfully built the Rust compiler with the GCC backend. One more step toward having GCC as an alternative backend codegen alongside LLVM and Cranelift. :) If you want to try it out, here's the branch: github.com/GuillaumeGom... Instructions on how to build it: 1/2

Rust was once again named the most admired programming language in the Stack Overflow #DevSurvey! 🦀 Great to see Cargo, Rust’s package manager, also mentioned as one of the most loved tools—a strong signal that thoughtful, dependable tooling matters.

Alright, it's time for some serious #bevy project management. Our planned 0.17 release candidate date of August 4th is approaching quickly, and we still have an alarming 78 issues and PRs in our milestone: github.com/bevyengin...#bevy Surely we can get that number down, right?

I have wrote yet another article about compiling Rust with GCC. fractalfir.github.io/generated_ht... I go over some neat news(running the Rust compiler on M68K CPUs), important topics(eg. how we test `cg_gcc`, or ABI compatiblity), and some fun triva about cursed proc-macros. Hope you enjoy it!

Two (very) nice improvements got merged today in docs.rs: 1. Content is now streamed directly from storage, allowing a much smoother experience for users: github.com/rust-lang/do... 2. You can search for Rust project crates like `std` on docs.rs search directly: github.com/rust-lang/do... Enjoy!

In rust, if the macro expansion failed, you get a lot of errors related to the missing macro expansion, which is just noise basically. I implemented in github.com/rust-lang/ru... a check to stop compilation if a macro expansion failed, greatly reducing the number of noisy errors. Enjoy!

Doc aliases in rust documentation search now support fuzzy matching, like all other items (try to search for `getcwd` here: doc.rust-lang.org/nightly/std/...). Enjoy! PR: github.com/rust-lang/ru...

Add a new API to get the name of any lvalue in GCC. Merged it into the Rust's fork of GCC and patch sent to GCC. It should allow us to improve the Rust GCC backend. :) PRs: github.com/rust-lang/gc... github.com/rust-lang/gc...

Just published the 0.36.1 version of the Rust sysinfo crate (to retrieve system information). It contains an improvement on processors CPU usage computation on Linux. crates.io/crates/sysinfo
