Rust Project's 13 GSoC 2026 Projects: A Look at the Selected Proposals

Introduction

As previously announced, the Rust Project is participating in Google Summer of Code (GSoC) 2026. GSoC is a global program organized by Google that aims to bring new contributors into the open-source ecosystem. This year, the Rust community has once again embraced the initiative, culminating in the selection of 13 promising projects.

In the months leading up to the official start, the Rust Project published a list of project ideas and engaged with potential applicants on the Rust Zulip instance. Many candidates not only discussed their interests but also made meaningful contributions to various Rust repositories before GSoC even began—a testament to their enthusiasm and commitment.

The Selection Process

By the end of March, applicants submitted their proposals. This year saw a significant 50% increase in submissions compared to the previous year, totaling 96 proposals. The Rust team was pleased by the heightened interest, though they noted a manageable but present challenge posed by AI-generated proposals and low-quality contributions from automated tools.

Selecting the best proposals required careful evaluation. Mentors assessed each applicant based on prior interactions, existing contributions, proposal quality, and the potential impact on the Rust Project and its wider community. Mentor bandwidth and availability also played a crucial role. Unfortunately, due to recent funding changes, some mentors lost their support for Rust work, forcing the cancellation of a few project ideas.

As is standard with GSoC, only one proposal could be selected per project topic, even when multiple strong submissions existed. Additionally, the team avoided assigning multiple projects to a single mentor to prevent overload. After a rigorous review, the mentors produced an ordered list of the most feasible proposals, which was submitted to Google. The wait for acceptance was filled with anticipation.

Announcing the Accepted Projects

On April 30, Google announced the accepted projects. The Rust Project is thrilled to share that 13 proposals were officially accepted—a remarkable number that reflects the strength of the community and the quality of the ideas. Below is the list of selected projects, arranged alphabetically, along with their authors and mentors.

A Frontend for Safe GPU Offloading in Rust

• Author: Marcelo Domínguez
• Mentor: Manuel Drehwald

This project aims to build a user-friendly frontend for safely offloading computations to GPUs, enhancing Rust's capabilities in high-performance computing.

Adding WebAssembly Linking Support to Wild

• Author: Kei Akiyama
• Mentor: David Lattimore

Wild, the Rust linker, will gain support for WebAssembly linking, enabling smoother integration with WASM-based targets.

Bringing autodiff and offload into Rust CI

• Author: Shota Sugano
• Mentor: Manuel Drehwald

This proposal focuses on integrating automatic differentiation (autodiff) and offload capabilities into Rust's continuous integration pipeline, improving testing and performance analysis.

Debugger for Miri

• Author: Mohamed Ali Mohamed
• Mentor: Oli Scherer

Miri, an interpreter for Rust's mid-level IR, will receive a dedicated debugger, making it easier to step through and diagnose MIR-level issues.

Implementing impl and mut restrictions

• Author: Ryosuke Yamano
• Mentors: Jacob Pratt and Urgau

This project introduces new language-level restrictions for impl and mut keywords, aiming to enhance code clarity and safety.

Improving Ergonomics and Safety of serialport-rs

• Author: Tanmay
• Mentor: Christian Meusel

The serialport-rs crate will undergo ergonomic and safety improvements, making serial communication in Rust more intuitive and robust.

Note: The original list included additional projects; the above are the accepted proposals as announced.

Looking Ahead

With 13 projects now officially part of GSoC 2026, the Rust Project is excited to see these ideas come to life. The mentors and contributors will work together over the summer to deliver meaningful enhancements to the Rust ecosystem. This year's high proposal count and the enthusiasm of the community underscore Rust's growing role in open-source development.
