Compiling Rust to readable C with Eurydice
The Eurydice project aims to compile Rust code into readable C, facilitating the use of Rust in high-assurance software environments. By bridging the gap between modern memory-safe languages and legacy verification tools, it supports safer software development.
Why it matters
It addresses a significant technical barrier for industries like cryptography and formal verification that require C-based compliance but want to leverage Rust's safety features.
We can admit it, marketing is not our strong suit. Our strength is writing the kind of articles that developers, administrators, and free-software supporters depend on to know what is going on in the Linux world. Please subscribe today to help us keep doing that, and so we don’t have to get good at marketing. By Daroc Alden January 30, 2026 A few years ago, the only way to compile Rust code was using the rustc compiler with LLVM as a backend. Since then, several projects, including Mutabah's Rust Compiler (mrustc), GCC's Rust support (gccrs), rust_codegen_gcc , and Cranelift have made enormous progress on diversifying Rust's compiler implementations. The most recent such project, Eurydice , has a more ambitious goal: converting Rust code to clean C code. This is especially useful in high-assurance software, where existing verification and compliance tools expect C.
