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. I'll probably still be occasionally reviewing and contributing, but I don't have any energy left to stay involved as much as I used to. At least for now.

I'll still be a member of the Rust project, as part of the leadership council and organization of the Rust All-Hands 2026.

I'm excited to find something new that gives me energy and motivation. Most likely, that new thing will have something to do with Rust, but I don't know yet what exactly that will be. Maybe teaching Rust, or writing another book, or solving #burnout in open source.. we'll see. :)

Thanks to everyone who I worked with on the Rust standard library and language. It has been a pleasure. Our paths will definitely cross again. 💛

Yeah, so #PyPy 3.12 support won't enter #Gentoo for a while, because it needs support in #PyO3 first (because of the brilliant idea that #Hypothesis should require it), so we're blocked on the whole #RustLang / #Cargo "implement, release and wait for everyone to update their pins" nonsense.

If you're intrigued by what kind of tweaks rustc gets on the regular, here's a small thing that should aid in reading some diagnostics. Some time back I discussed with @muscraft that I've wanted a way to ensure some code appears in diagnostics, but not underline them, because they are useful context but unrelated to the problem. Over time, he proceeded to implement that feature in annotate-snippets-rs *and* migrate rustc to use that crate (closing a ton of tickets for incorrect rendering or inconsistencies, the current codebase for that crate is much better than rustc's ever was). So now that we have that new toy, I've been going around using it! And if I may say so myself, I think it works great:

It's Friday again, so it's time for another update on the work on Diesel, a ORM and query-builder for Rust.

This week I released diesel-full-text-search 2.3.1 fixing a potential unbound allocation while deserializing a malformed buffer from the database.

I also released pq-sys 0.7.6 and pq-src 0.3.12/13 to fix copying the right bindings file for builds using *-pc-windows-gnu targets and to bump the bundled libpq version to 18.6.

See the release announcement for more details:

https://github.com/diesel-rs/diesel_full_text_search/releases/tag/v2.3.1
https://github.com/sgrif/pq-sys/releases/tag/v0.7.6

This week we received two new bug reports and 17 new PR's.

This issue was found with the help of AI, namely GPT-6 Astra.

In skilled hands, AI is an extraordinary tool for detecting bugs, unsoundness, and security vulnerabilities.

*Everything* is buggy, it turns out. Neither people nor AI are above writing buggy code — and now we have ability to find many of those bugs.

You don't have to use AI to write code if you don't want to. But know that the bar for quality and correctness will go *up* as a result of skilled AI use, and most of that AI use will be far more interesting than just writing new code.

GitHub Actions + Rust's Miri can leak your secrets in CI 🧵

If you run Miri in CI:
- upgrade to the 2026-09-22 nightly
- clear caches
- rotate any secrets that the `cargo miri` CI job had access to

https://blog.rust-lang.org/2026/09/21/github-actions-leaking-secrets-when-miri-output-is-cached/

#rust #rustlang #miri #githubactions #security #vulnerability

GitHub Actions makes it possible to cache directories between runs. Typical setups allow CI runs on main (and other branches) to write to cache, and PRs can only read from cache (preventing cache poisoning). Rust projects tend to speed up CI by caching binaries built by cargo install and sometimes the contents of target/. PR CI can be triggered by anyone who can open PRs on your repository. GitHub requires maintainer approval for the first PR, but future PRs will rerun CI on every push. Anyone who has previously landed a change can trigger a CI run extracting information from cached target/ and then cover their tracks by pushing a second commit to the PR. GitHub sometimes hides overwritten commits in its UI, making this kind of attack harder to detect. CI run logs and overwritten commits are also deleted after a few months. When cargo miri is invoked, Miri needs to retain build-relevant environment variables between runs. The current code to do so achieves this by storing all environment variables to target/. This, of course, persists when target/ is cached. If your environment contained secrets, these can now be accessed by PRs via the cache.
