Rust Project Joins Outreachy for May 2026 Cohort, Selects Four Interns for Diversity-Focused Mentorship

The Rust Project has announced its participation in the Outreachy open-source internship program for the May 2026 cohort, selecting four interns to work on critical compiler and language tooling projects. This marks the project's first involvement with Outreachy, a program designed to support individuals from underrepresented backgrounds in tech.

"We are thrilled to welcome four talented interns through Outreachy," said a Rust Project spokesperson. "This program aligns perfectly with our commitment to fostering diversity and inclusion in open source."

How Outreachy Differs from Google Summer of Code

Outreachy operates similarly to Google Summer of Code (GSoC) but with distinct eligibility and application processes. Unlike GSoC, interns first apply to the overall program before selecting specific communities, and contributions during a dedicated period are mandatory, not optional.

Another key difference: communities fund intern stipends directly in Outreachy, whereas Google covers stipends for GSoC. The Rust Project chose to participate in both programs this year, having also been part of GSoC for three consecutive years.

Selected Interns and Their Projects

Due to limited funding and mentoring capacity, the Rust Project selected four interns for the May 2026 cohort. Below are the projects and mentors for three of them; details on the fourth will be shared soon.

Calling Overloaded C++ Functions from Rust

Intern: Ajay Singh, Mentors: teor, Taylor Cramer, and Ethan Smith. This experimental feature aims to enable Rust code to directly invoke overloaded C++ functions, with initial testing in representative use cases.

Code Coverage of the Rust Compiler at Scale

Intern: Akintewe Oluwasola, Mentor: Jack Huey. The project will develop workflows to run and analyze compiler code coverage across the full test suite and ecosystem crates, aiming to detect inadequately tested areas and build continuous analysis tools.

Fuzzing the a-mir-formality Type System Implementation

Intern: Tunde-Ajayi Olamiposi, Mentors: Niko Matsakis, Rémy Rakic, and tiif. This effort focuses on implementing fuzzing for a-mir-formality, an in-progress model for Rust's type and trait system, to uncover edge cases and improve robustness.

Background

The Rust Project has built a strong record in open-source mentorship, having participated in Google Summer of Code for three years and previously in the OSPP program. The addition of Outreachy demonstrates a broader commitment to inclusive community engagement and skill development.

"Our experience with GSoC showed us the value of structured mentorship," added the spokesperson. "Outreachy expands our reach to talented individuals who may face systemic barriers in tech."

What This Means

Joining Outreachy reinforces Rust's dedication to building a diverse and welcoming open-source ecosystem. By funding internships directly, the project invests in contributors who bring fresh perspectives to compiler design and tooling.

The selected projects—from C++ interop to fuzzing—target critical areas for Rust's long-term reliability. This initiative is expected to not only advance these specific features but also create pathways for sustained community involvement from underrepresented groups.
