7 Essential Facts About Rust's New Outreachy Program and Its 4 Intern Projects

The Rust Project has steadily built a tradition of nurturing new contributors through open-source mentorship initiatives. After multiple successful years with Google Summer of Code (GSoC) and previous involvement with OSPP, the community is now expanding its reach. Starting with the May 2026 cohort, Rust will also participate in Outreachy—a program designed to support individuals from underrepresented groups in tech. Each mentorship initiative has its own eligibility focus, and Outreachy specifically targets people who face systemic bias or discrimination in their local tech industry. This article walks you through the key aspects of Rust's new Outreachy involvement, how it differs from GSoC, and introduces the four promising interns and their projects. Whether you're curious about applying or just want to understand the program's impact, here are seven things you should know.

1. Rust Joins Outreachy for the First Time

The Rust Project has announced its participation in the Outreachy program, beginning with the May 2026 internship cohort. This marks a new chapter for Rust's mentorship ecosystem, complementing its long-standing involvement with Google Summer of Code and the OSPP initiative. Outreachy's mission is to create opportunities for people from any background who face underrepresentation, systemic bias, or discrimination in the technical industry where they live. By joining this program, Rust aims to welcome diverse perspectives and skills into its community. The program provides a structured environment for contributors to work on real-world open-source projects while receiving support and guidance from experienced mentors.

2. Understanding Outreachy's Unique Application Process

Outreachy differs from many other internship programs in how applicants engage. First, prospective interns apply to the overall Outreachy program before they can select specific communities like Rust. This centralized initial screening ensures all participants meet the program's eligibility criteria. Once accepted into the program pool, applicants then identify projects and communities they wish to join. Second, Outreachy mandates a dedicated contribution period where applicants must demonstrate their skills and commitment through tangible contributions—this is not optional but a required step before final selection. Finally, applicants submit a formal application similar to GSoC, and communities choose interns based on both the application and the quality of contributions. This process ensures a fair and thorough evaluation.

3. Key Differences Between Outreachy and GSoC

While Outreachy and Google Summer of Code share similarities—both are remote internships on open-source projects—they have critical distinctions. The most notable difference lies in how stipends are funded. For GSoC, Google covers all intern stipends and program overhead. In contrast, Outreachy requires each participating community to fund its own interns' stipends and administrative costs. This places a financial responsibility on projects like Rust, which must raise or allocate funds to support their selected interns. Another difference is the timing: Outreachy runs two cohorts per year (May–August and December–March), whereas GSoC usually has one annual cycle. Additionally, as mentioned, Outreachy mandates contributions during a specific application period, while GSoC makes contributions optional. These differences make Outreachy a distinct and valuable opportunity for both communities and interns.

4. Rust Is Mentoring Four Interns in the May 2026 Cohort

Due to limited funding and mentoring capacity, the Rust Project has chosen to support four outstanding interns for the May 2026 Outreachy session. Each intern works on a focused project that addresses a real need in the Rust ecosystem. The selected projects span from improving C++ interoperability to enhancing compiler testing and formal verification. Below, we highlight each intern, their mentors, and the goals of their work. These projects not only advance Rust's technical capabilities but also provide a rich learning experience for the interns involved.

5. Project 1: Calling Overloaded C++ Functions from Rust

Intern: Ajay Singh | Mentors: teor, Taylor Cramer, Ethan Smith
This project aims to implement an experimental feature that enables Rust to call overloaded C++ functions. C++ function overloading is a common pattern in existing codebases, yet Rust has no direct way to disambiguate overloads. By developing this feature and testing it on representative use cases, the project will improve interoperability between Rust and C++. This work could unlock seamless integration with many legacy C++ libraries, making Rust more accessible for projects that need to interoperate with existing C++ code. Early testing will focus on a few practical examples to validate the approach.

6. Project 2: Code Coverage of the Rust Compiler at Scale

Intern: Akintewe Oluwasola | Mentor: Jack Huey
This project focuses on developing workflows to run and analyze code coverage for the entire Rust compiler test suite and ecosystem crates detected by the crater tool. The goal is to detect areas of the compiler that are inadequately tested—both within the compiler itself and across the broader ecosystem. By building tools for continuous analysis, the project will help maintain high code quality and guide future testing efforts. This is a crucial step for ensuring the compiler remains robust as Rust grows.

7. Project 3 & 4: Fuzzing a-mir-formality and More

Interns: Tunde-Ajayi Olamiposi and another intern (project details pending) | Mentors: Niko Matsakis, Rémy Rakic, tiif, plus others
The third project involves implementing fuzzing for a-mir-formality, an in-progress model for Rust's type and trait system. Fuzzing will help uncover edge cases and ensure the model's correctness. A fourth project (to be announced) will complement these efforts. Together, these projects strengthen Rust's foundation by improving both tooling and formal verification processes.

Rust's participation in Outreachy represents a significant step toward a more inclusive and robust open-source ecosystem. By supporting diverse voices and tackling meaningful technical challenges, the community continues to grow stronger. We look forward to seeing the results of these projects and encourage interested readers to explore future Outreachy cohorts. Back to top
