Rust Project Joins Outreachy 2026, Selects Four Interns for Open Source Mentorship

The Rust Project is expanding its mentorship footprint by participating in Outreachy for the May 2026 cohort, selecting four interns to work on critical compiler and tooling improvements. This marks the first time the project has joined the program, which focuses on supporting underrepresented groups in tech.

“Outreachy aligns with Rust’s commitment to fostering a diverse and inclusive community,” said a Rust Project spokesperson. “We’re excited to bring in fresh perspectives through structured, contribution-driven internships.”

What Makes Outreachy Different from Google Summer of Code

While Rust has participated in Google Summer of Code (GSoC) for three years, Outreachy introduces a distinct application process. Interns must first apply to the overall program, then to specific communities. A dedicated contribution period is mandatory, not optional.

Another key difference: stipends are funded by participating communities rather than by Google. “This shift in funding model requires more from us, but it also gives us greater ownership of the mentorship experience,” the spokesperson added.

Four Projects Selected for May 2026 Cohort

Due to limited funding and mentoring capacity, the Rust Project selected four projects. Below is a brief overview of each.

Calling Overloaded C++ Functions from Rust

Intern: Ajay Singh, mentored by teor, Taylor Cramer, and Ethan Smith. This project implements an experimental feature for calling overloaded C++ functions from Rust, with initial testing in representative use cases.

Code Coverage of the Rust Compiler at Scale

Intern: Akintewe Oluwasola, mentored by Jack Huey. The goal is to develop workflows to run and analyze code coverage across the entire compiler test suite and ecosystem crates detected by Crater. This will help detect inadequately tested areas.

Fuzzing the a-mir-formality Type System Implementation

Intern: Tunde-Ajayi Olamiposi, mentored by Niko Matsakis, Rémy Rakic, and tiif. This project aims to build fuzz testing for a-mir-formality, an in-progress model for Rust’s type and trait system.

Fourth Project Pending Announcement

The Rust Project has confirmed four interns but will disclose the fourth project separately. Details are expected closer to the May start date.

Background

Outreachy provides paid internships in open source to people facing underrepresentation, systemic bias, or discrimination in the technical industry. The program runs twice yearly: May to August and December to March.

Rust has previously participated in GSoC and OSPP. “We’ve learned a lot from those programs, and Outreachy gives us a chance to reach a different audience,” the spokesperson noted. The application process requires substantial contributions before selection.

What This Means

By joining Outreachy, Rust signals its dedication to lowering barriers for marginalized groups in open source. The selected projects address practical challenges like C++ interoperability, testing infrastructure, and type system verification—all crucial for Rust’s growth.

“These are not toy problems,” said a mentor quoted in the materials. “We expect real, impactful contributions that will benefit the entire ecosystem.” The program also strengthens Rust’s pipeline for future maintainers and contributors.
