About:
C2Rust is a tool that assists in migrating C codebases to Rust, focusing on interoperability and safety. It first generates idiomatic Rust code from C source files, then helps developers incrementally refactor the output to leverage Rust's memory safety guarantees. This tool is invaluable for modernizing legacy C projects while maintaining correctness.
Key Features:
  • Transpiles C code to Rust
  • Refactoring tools for memory safety
  • Supports large, existing codebases
  • Maintains interoperability with C libraries
Use Cases:
  • Migrating legacy C applications to Rust
  • Improving memory safety in existing C projects
  • Automating code translation for modernization
Alternatives:
  • bindgen – Generates Rust FFI bindings for C libraries, but does not transpile full codebases.
  • c2rust-refactor – A deprecated predecessor; C2Rust is the actively maintained successor.
