port-c-module

What problem does it solve?

This Skill helps engineers port a C module to Rust by providing a structured, step-by-step guide that covers analysis, planning, Rust crate creation, FFI integration, and testing to reduce porting risk and improve safety.

Core Features & Use Cases

• Porting plan framework: Create a porting plan document detailing decisions, interfaces, and migration milestones.
• Rust crate scaffolding: Set up a pure Rust crate to host the ported logic and safe abstractions over the C API.
• FFI boundary and interop: Implement a robust C-FFI wrapper to expose Rust functionality to the C codebase and replace or wrap legacy calls.
• Testing and integration: Provide guidance to run unit and integration tests to validate behavior across languages.

Quick Start

Port the C module to Rust by creating a new Rust crate, adding a porting plan, implementing the Rust logic, creating an FFI boundary, and wiring it into the C build system, then run tests.
