The Rust Programming Language Blog: Rust is participating in Outreachy

The Rust Project has been building up a good history of participating in various open-source mentorship programs, including . We're happy to announce that this year we are also participating in .

We are mentoring 4 interns for the May 2026 cohort

Because of limited funding availability and mentoring capacity, the Rust Project decided to select four interns for mentorship. We'll briefly share these projects below.

Code coverage of the Rust compiler at scale

.

This project aims to develop the workflows to run and analyze code coverage of the compiler at the scale of the entire compiler test suite and on ecosystem crates detected by crater. The hope is to be able to detect when the compiler is inadequately tested, both within the compiler and in the ecosystem, and to build tools to do continuous analysis on this.

This project aims to improve the security of GitHub Actions workflows of the repositories owned by the Rust Project. It will develop tools and workflows, integrating with existing software, to analyze Github repositories and detect if they follow the best security practices, fix existing issues, and ensure that good security practices are followed in the future.

What's next

Over the next 3 months, the interns will work closely with their mentors to make progress on their projects. When the internship period is over, we'll write another blog post to share the results! See you then!

We also want to thank all the people that submitted applications and made contributions. It was quite tough to decide which applicants to select. Hopefully we will participate in Outreachy again in the future and there are other opportunities to participate. We also very much welcome you to stick around and continue being involved - there is a ton of places in the Rust Project with opportunities to be involved.
