Rust Project Joins Outreachy: Everything You Need to Know

The Rust Project has a strong track record of supporting open-source mentorship, having participated in Google Summer of Code for three years and previously in OSPP. Now, for the May 2026 cohort, they are expanding their efforts by joining Outreachy. This program is designed to support people from underrepresented groups in tech. Below, we answer common questions about this initiative, the application process, and the specific projects Rust will mentor.

What is Outreachy and how is it different from Google Summer of Code?

Outreachy is an internship program that provides opportunities in open source for people facing underrepresentation or discrimination in tech. While similar to Google Summer of Code (GSoC), there are key differences. First, Outreachy applicants must first be accepted into the overall program before they can apply to specific communities. Second, contributions are mandatory during a dedicated period before applications are submitted, whereas in GSoC they are optional. Third, the funding source differs: GSoC stipends are covered by Google, but for Outreachy, each participating community pays for its interns' stipends and overhead. Outreachy runs two cycles per year: May to August and December to March.

Why is the Rust Project joining Outreachy?

The Rust Project has a well-established history of fostering new contributors through mentorship programs like Google Summer of Code and OSPP. By joining Outreachy, they aim to broaden access to open-source development for individuals from underrepresented backgrounds, in line with the project's commitment to inclusivity. This move also helps Rust tap into a wider talent pool and strengthens its community by bringing in fresh perspectives. The limited funding and mentoring capacity led the project to select four interns for the May 2026 cohort, focusing on impactful projects that advance the Rust ecosystem.

Who is eligible to apply for Outreachy?

Outreachy targets individuals from backgrounds that face underrepresentation, systemic bias, or discrimination in the technical industry where they live. This includes, but is not limited to, people of color, women, LGBTQ+ individuals, and others who are historically marginalized in tech. Unlike some programs that have age or student-status restrictions, Outreachy welcomes applicants from all walks of life, provided they meet the program's general eligibility criteria as detailed on the Outreachy website. The application process involves an initial submission to the program, followed by a contribution period with the chosen community.

How does the Outreachy application process work for Rust?

The process begins with applicants applying to the Outreachy program as a whole. Once accepted, they can then apply to specific communities like Rust. A key requirement is a dedicated period where applicants must make contributions to the community they are interested in—these contributions are not optional, unlike in Google Summer of Code. For Rust, potential interns submit a final application that includes details about their contributions. The Rust Project's mentors then select interns based on these applications and the quality of the contributions. This approach ensures that interns have practical experience with the project before starting.

What are the four internship projects for the May 2026 cohort?

The Rust Project has selected four interns for this cohort, each working on a distinct project:

Calling overloaded C++ functions from Rust – Mentored by teor, Taylor Cramer, and Ethan Smith, this project by Ajay Singh aims to implement an experimental feature for calling overloaded C++ functions from Rust and test it in representative use cases.
Code coverage of the Rust compiler at scale – Mentored by Jack Huey, Akintewe Oluwasola will develop workflows to run and analyze code coverage of the compiler across the entire test suite and ecosystem crates detected by crater, aiming to detect inadequate testing.
Fuzzing the a-mir-formality type system implementation – Mentored by Niko Matsakis, Rémy Rakic, and tiif, Tunde-Ajayi Olamiposi will implement fuzzing for a-mir-formality, an in-progress model for Rust's type and trait system.
(Fourth project description incomplete in original announcement) – The Rust Project plans to mentor a fourth intern, but details were cut off in the original text. Check the official Rust blog for updates.

Who funds the Outreachy interns?

Unlike Google Summer of Code, where Google covers all stipends and overhead, Outreachy requires participating communities to fund their own interns. For the Rust Project, this means raising money to support the internship stipends and administrative costs. The project decided to select only four interns due to limited funding availability and mentoring capacity. This funding model allows communities to tailor the program to their needs but also places a financial responsibility on them. Rust's commitment to Outreachy demonstrates their willingness to invest in diversity and inclusion initiatives.
