c2rust
A transpiler that migrates C99-compliant code to unsafe Rust, preserving functionality and enabling incremental refactoring.
What is c2rust?
C2Rust is a transpiler that converts C99-compliant code into unsafe Rust, enabling the migration of legacy C projects to the Rust ecosystem. It focuses on preserving the original functionality so that existing test suites continue to pass after translation. The project also includes refactoring tools to help developers incrementally improve the safety and idiomatic quality of the generated Rust code.
Developers and teams maintaining legacy C codebases who want to migrate to Rust for memory safety and modern tooling, particularly those working on systems software, libraries, or embedded projects.
C2Rust provides a pragmatic, incremental path to Rust adoption by automating the initial translation of C code, which can then be refined. Its integration with standard build systems and focus on correctness makes it a practical choice for real-world migration projects.
