Rust Expands Open Source Mentorship: Joins Outreachy for May 2026 Cohort
Rust Project leadership announced today that the language's community will participate in the Outreachy internship program for the first time, starting with the May 2026 cohort. This expands beyond its established involvement in Google Summer of Code (GSoC) and the Open Source Promotion Plan (OSPP). Four interns have been selected for the upcoming cycle, focusing on compiler tooling, fuzzing, and C++ interoperability.
"We're excited to welcome Outreachy interns into the Rust ecosystem," said a Rust Project spokesperson. "This program aligns with our commitment to diversity and inclusion, providing opportunities for individuals from underrepresented backgrounds in tech."
Background: Outreachy vs. Google Summer of Code
Outreachy, like GSoC, is a structured open-source internship program. However, it differs in key ways. Interns must first apply and be accepted to the overall program before applying to specific communities. A dedicated contribution period is mandatory before final selection.
Another major distinction is funding: Google covers stipends and overhead for GSoC, but for Outreachy, participating communities—like the Rust Project—fund their interns directly. This financial commitment reflects the project's dedication to fostering diverse talent.
What This Means
The inclusion of Outreachy signals Rust's push to lower barriers for newcomers from marginalized groups. The program targets individuals facing underrepresentation, systemic bias, or discrimination in the tech industry.
By funding four interns, Rust strengthens its pipeline of contributors from varied backgrounds. This move also diversifies the mentorship ecosystem alongside GSoC, potentially introducing new perspectives into core compiler and tooling development.
May 2026 Cohort Projects and Mentees
Due to limited funding and mentoring capacity, the Rust Project selected four interns. Three projects have been publicly detailed:
- Calling overloaded C++ functions from Rust – Intern Ajay Singh, mentored by teor, Taylor Cramer, and Ethan Smith. This experimental feature will allow Rust code to invoke overloaded C++ functions, with initial testing in representative use cases.
- Code coverage of the Rust compiler at scale – Intern Akintewe Oluwasola, mentored by Jack Huey. The project aims to develop workflows for running and analyzing compiler coverage across the entire test suite and ecosystem crates, using crater for detection of inadequately tested areas.
- Fuzzing the a-mir-formality type system implementation – Intern Tunde-Ajayi Olamiposi, mentored by Niko Matsakis, Rémy Rakic, and tiif. This initiative will implement fuzzing for a-mir-formality, an in-progress model of Rust's type and trait system, to uncover correctness issues.
A fourth intern's project will be announced soon, the spokesperson noted.
All internships run from May to August 2026, aligning with Outreachy's first cohort of the year. Mentors will guide interns through contributions that could eventually become part of the Rust codebase.
