How to use Corrode with an existing makefile?

Set CC=corrode-cc in your makefile, as the script mimics gcc to handle translation and compilation in one step, preserving build system commands without modification.

Corrode vs c2rust: which is better for C to Rust translation?

Corrode focuses on semantics preservation and ABI compatibility with GCC-like interface, while c2rust may offer more features for complex codebases; Corrode's output requires more manual cleanup for Rust idioms.

How does Corrode handle undefined behavior in C code?

Corrode picks reasonable behaviors, like using Rust's + operator for signed additions that might overflow, which panics in debug builds—but this doesn't guarantee safety without manual review.

Can Corrode translate C++ code to Rust?

No, Corrode is designed only for C source files and does not support C++ syntax, classes, or templates, limiting its use for mixed-language codebases.

What's the biggest limitation when using Corrode for real projects?

The tool is still experimental and may fail on complex C constructs; plus, the output isn't idiomatic Rust, so you'll spend time refining code rather than relying on automation.

How to install Corrode on macOS or Linux?

Clone the repository, install Haskell tools like Cabal or Stack, then run cabal install or stack install—there are no pre-built binaries, so expect setup time for dependencies.

corrode — C to Rust Translator

What is corrode?

Corrode is an automatic translator that converts C source code into semantically equivalent Rust syntax. It helps developers migrate legacy C codebases to Rust by preserving the original behavior and ABI compatibility, though the output requires manual cleanup to adopt Rust idioms.

Target Audience

Developers and teams maintaining legacy C codebases who want to migrate to Rust incrementally, or those exploring automated translation for research or tooling purposes.

Value Proposition

Corrode provides a reliable, semantics-preserving foundation for C-to-Rust migration, ensuring ABI compatibility and structural fidelity, which reduces manual rewriting effort and maintains link compatibility with existing C binaries.

C to Rust translator

Use Cases

Best For

Incrementally migrating large legacy C codebases to Rust
Generating Rust bindings for C libraries with precise semantics
Research or education on C and Rust semantics equivalence
Automating initial translation steps in C-to-Rust conversion projects
Integrating C code into Rust projects while preserving ABI compatibility
Testing Rust compilation paths for generated code from C sources

Not Ideal For

Projects requiring production-ready, idiomatic Rust code without manual refinement
Small C codebases where a full rewrite in Rust would be more time-efficient than translation and cleanup
Teams lacking Haskell development environment or unwilling to manage build-from-source dependencies
Migrations needing complete C language coverage or support for complex C11/C17 features

Pros & Cons

Pros

Semantics and ABI Preservation

Generates Rust code that behaves identically to the original C if free of undefined behavior, with extern 'C' modifiers ensuring link compatibility with C binaries.

Build System Compatibility

Accepts GCC compiler flags like -I and -D, and includes corrode-cc script to replace gcc in makefiles, enabling seamless integration into existing workflows.

Structural Fidelity

Maintains the original code structure and statement order, making the output recognizable and easier to maintain during migration.

Early Migration Automation

Automates the initial translation step for large legacy codebases, reducing manual rewriting effort while preserving behavior.

Cons

Non-Idiomatic Output

The generated Rust code lacks Rust idioms and safety features, requiring significant manual cleanup—a gap the README acknowledges with plans for a separate 'idiomatic' tool.

Incomplete C Support

The project is in early phases and admits it cannot translate most real C programs, relying on contributions to implement more language features.

Complex Setup Process

No pre-built binaries are available; users must build from source using Haskell tools like Cabal or Stack, which adds overhead and potential environment issues.
