rust-ffi-bindings

What problem does it solve?

This Skill helps Rust developers design safe, portable FFI bindings to expose Rust libraries to other languages by enforcing boundary safety, ABI-stable layouts, and clear ownership semantics.

Core Features & Use Cases

• Safety at the boundary: catch panics, validate inputs, and prevent undefined behavior when crossing language boundaries.
• ABI stability: use #[repr(C)] on exported types and stable enums to ensure consistent memory layouts across languages.
• Memory ownership & error handling: define explicit ownership models and robust error codes to communicate failures across FFI.
• Binding patterns for multiple targets: C API exports, C# bindings, Python bindings (PyO3), WebAssembly bindings (wasm-bindgen), and UniFFI multi-language bindings.
• Use cases: expose a Rust core (e.g., chart data structures) to C, Python, and JS environments for broader integration.

Quick Start

Install the Rust toolchain, annotate your exported APIs with extern "C" and #[repr(C)], implement panic-safety wrappers, and generate or wire up bindings with UniFFI, wasm-bindgen, or CsBindgen as needed.
