The end of the year is a time for reflection, so I thought that I should take a look back at the previous year. And since my main job is currently contributing to open-source, what better way to do that than enumerating all the Rust pull requests that I opened in 2025. In this post, I’ll share stats about my Rust contributions from the past year and also some thoughts about open-source (Rust) maintenance, as this topic is highly relevant right now.

First, some statistics. The GitHub GraphQL API claims that:

  • I opened 1497 PRs in 2025 (+98% from 755 opened PRs in 2024).
    • 1160 (77.49%) out of those were relevant to the rust-lang organization or other upstream Rust work1. I only consider these in this post.
    • I contributed to 50 different upstream-Rust-related repositories in the past year.
  • I reviewed 976 PRs in 2025 (+131% from 421 reviewed PRs in 2024).
    • 753 (77.15%) out of those were relevant to upstream Rust2.

I used this script to calculate these statistics.

When I saw these numbers, I was quite surprised. It felt like too much, and I had to go double-check the script I used to compute it. But after examining the list of my opened PRs, and thinking a bit more about my Rust contributions, it started making sense. The high number of PRs that I open(ed) stems from the fact that the kind of work I usually do in Rust is quite maintenance-heavy3. As a member of the Rust Infrastructure team, I do many small and drive-by contributions to various repositories to fix CI, update configs or docs, set up some tooling, etc. I definitely couldn’t open a thousand PRs in a year if they were all implementations of new compiler/languages features or something like that4.

A lot of that work can be quite unglamorous, like doing house chores. There are probably less than 50 pull requests from the past year that I could show to someone and say “here, I did something cool”. The rest is mostly work that “had to be done”. And there’s a lot of that work! Even though 1160 PRs might sound like a lot, it is just a drop in the ocean in the upstream Rust world. In 2025, just the rust-lang/rust repository received 10483 (!) pull requests5. I personally opened only 307 out of those PRs. That shows just how much work goes into maintaining Rust (and note that this is just a single repository, although the most important and extensive one that we have). I try to help this effort by often (but not always) prioritizing unblocking other Rust Project contributors, rather than pushing my own work forward, as that tends to have a larger effect down the line.

It should also be noted that opening pull requests is just a fraction of the work that a typical open-source contributor/maintainer does. There are certainly many other activities that I do, such as code reviews, writing and reading design docs, discussing various ideas with other people on Zulip and GitHub, reading and writing blog posts, triaging issues, governing and making decisions, listening to podcasts to find inspiration, attending and talking at conferences, watching recordings of conference talks that I didn’t see live or thinking about compiler optimizations while walking my dog :) Open-source is about communication as much as it is about writing code (and even that is a form of communication). So quantifying work based on just the number of opened pull requests does not paint the whole picture.

It can be quite hard to demonstrate the value of work like this, especially to companies. That is something that we are trying to improve with the Rust Foundation Maintainer Fund (and other similar efforts). Maintaining Rust so that it keeps working as well today as it did yesterday is a lot of work. And moving it forward by adding new features is even harder6. That is why I think that it is crucial to support contributors that maintain and develop Rust. Without them, Rust could not thrive and evolve.

While I am currently one of the lucky people who are funded for their upstream Rust work7, many Rust contributors do not have access to stable funding. While the Rust Foundation (together with the Rust Project) is currently trying to figure out how we can build a sustainable mechanism for funding full-time Rust maintainers, there are also more targeted ways to help fund individual contributors “in the small”. If you are feeling generous, consider sponsoring individuals who make Rust better on a daily basis.

Summary

Here is a short summary of a few things from 2025 that stand out (in no particular order). In 2025, I:

  • Was elected to the Leadership Council and invited to the compiler team.
  • Oversaw the Rust GSoC program again, this year with 19 (!) projects. I think that we did pretty well!
  • Attended RustWeek and the Rust All Hands, quite possibly the best conference/event I have ever been to.
    • Inspired by RustWeek, I wrote a blog post that shows the evolution Rust compiler error messages. I’m quite proud of that one, if I do say so myself :)
  • Helped move the initiative to use the LLD linker by default on Linux over the finish line, finally getting the great work of @lqd and others to a large fraction of Rust users.
  • Made a lot of progress on improving the Rust Compiler Benchmark Suite together with James Barford from ARM, as a part of one of Rust’s Project Goals. This reduced the time needed to wait for compiler benchmarks on our CI and opened the doors to benchmarking on more hardware architectures (e.g. ARM).
  • Spent an unhealthy amount of time peeking into the abyss of bootstrap (the Rust toolchain build system), refactoring it and making it at least somewhat consistent again after the Great stage0 redesign has landed. Much more work remains to be done there, though.
  • Helped prepare several surveys (Rust Compiler Performance survey, Rust Contributor survey, Leadership Council survey, Variadic Generics survey, Safety-critical survey and of course the State of Rust survey).
  • Made a lot of little improvements and reduced tech debt somewhat in our infrastructure and CI. By creating a tool to make git subtree synces easier and more robust, helping move our CI off the rust-lang-ci/rust repository (finally!), syncing crates.io crate owners in the team repo, moving the Rust web to a static website and adding some cool things to it, and implementing many improvements to our bots (mostly triagebot and bors).
  • Was able to make small progress on compiler performance. In addition to the already mentioned LLD linker stabilization, Compiler Performance survey and rustc-perf improvements, I made some improvements to visualizing what takes time in Rust builds, bootstrapped an official Cargo build performance guide, made a few drive-by performance improvements, and restarted important work on proc-macro caching8. I also had some big ideas for building tooling for better diagnostics of compiler performance and build times, but sadly did not have time to work on these since ~June. Lots of other things got in the way!
  • Made Rustup start ~3x faster by adding 6 lines to it. Kinda proud of that one :laughing:.
  • Made Rust Analyzer ~20% faster by implementing PGO for it and Clippy ~5% faster by switching it to use Jemalloc.
  • Implemented visualization of linking times in cargo build --timings output (not stabilized yet).
  • Wrote my first RFC (for the #[derive(From)] feature), got it accepted :tada: and implemented it. Although it will need to be landed over an edition due to some backwards incompatible name resolution issues, so it might take some time before it gets stabilized.
  • Participated in various funding discussions, helped prepare a design document for the Rust Foundation Maintainer Fund and created a dedicated Funding page on the Rust website, to make it easier to sponsor Rust Project contributors.
  • Had a talk about how Rust does open-source governance/maintenance at a local tech conference, gave some Rust talks at a few Rust meetups, led two Rust trainings and taught Rust at my university again.

It goes without saying that everything mentioned above was team work that couldn’t be done without the help of the awesome people who are Rust :heart:.

My 2025 Rust PRs

And here is the promised list of the Rust PRs that I opened in 2025. They are categorized by repository (repos are ordered by PR count in descending order) and within each repo they are ordered by creation time in ascending order. Unless otherwise noted, the pull request was merged, although I also kept the opened and closed ones, just to show the open/close/merge ratio.

Below the list you can find a few more thoughts on my 2025 Rust contributions and the conclusion.

A few more thoughts on my 2025 contributions

Looking back at the above list, I think I managed to do a lot of work. Even though after finally finishing my PhD I had a lot of energy and time to work on Rust at the beginning of the year, due to some new family responsibilities, teaching at a university, and doing a lot of “non-technical” work (like surveys, mentoring or governance), I felt a bit unproductive in the second half of the year. At least in terms of actual coding, which is still something that I enjoy the most and that “feels” the best, even though other kinds of work are also important.

In fact, my personal Rust TODO list grew (not shrank) in 2025, which is a bit depressing. A large part of that was likely caused by me trying to finish initiatives already started year(s) ago, which I didn’t have the bandwidth to drive forward during my PhD studies, and so new ideas had to wait.

It is also clear that I maintain perhaps definitely too many projects and initiatives. I think that is a good thing for the Rust Project, because I’m able to help maintain some things that would probably otherwise be unmaintained or stuck. However, I’m not sure if it’s such a good thing for myself. Even though I think that I’m relatively good at handling many initiatives at once9 and I’m used to context-switching many times per day hour, that doesn’t mean that I wouldn’t be (or at least feel) more productive and less stressed if I was working on a smaller set of projects at once. It is my short-to-medium-term goal to reduce the number of Rust projects that I contribute to, so that I can focus on things that I find the most impactful and most enjoyable for me to work on, such as compiler performance, which I didn’t get to at all for the past few months. The hard part, as always, is to find people that would continue to pass the torch so that things I “leave behind” don’t get stuck again.

One area where I’m thinking of scaling down my contributions is the Rust survey team. I mostly only joined it because it seemed like no one else would do it at the time. And even though I created some scripts to partly automate survey analysis, doing surveys doesn’t exactly spark joy to me, so I would like to pass the torch to others. But it’s tricky…

Conclusion

I hope you found this post interesting. I’m thinking of making this a regular yearly “look back” post (for as long as I’m able to work on Rust), so maybe see you here in a year :)

And in case anyone is wondering, none of the PRs listed above were vibe-coded. I don’t use AI much for normal development, although sometimes it is quite useful for creating one-off scripts, such as those I used for gathering my GitHub statistics.

If you found some other interesting new year open-source data visualizations, let me know on Reddit.

  1. It also includes a handful of contributions to the “Rust ecosystem”, i.e. Rust crates on crates.io that are outside the rust-lang organization. But there are not many of those, and I did not include PRs to my own crates, such as delegate or cargo-pgo. ↩

  2. It’s a bit funny how similar is the ratio of upstream Rust work in both my opened and reviewed PRs. ↩

  3. I plan to blog Soon™ about my definition of software maintenance, either on this blog or on the official Rust blog. Stay tuned. ↩

  4. Although I know people who can :grin:. ↩

  5. The first one was #134988. On average, it is more than 28 PRs opened per day. ↩

  6. I like to say that if you gave me a hundred full-time engineers, I would find all of them something to work on in the Rust toolchain immediately. ↩

  7. On average, I spend around 70% of my work time on Rust, and I am funded for all that. ↩

  8. Which is sadly kind of stuck on finding more people that understand this part of the compiler (or on becoming such a person myself). ↩

  9. In reality, I probably suck at it the same as everyone else does, but I don’t know how to operate in any other way, so I don’t have a baseline to compare to. I also kind of suck at working on a single thing for a long time, which is probably why I cling to context switching so much, almost as a form of procrastination. ↩
