nim-c-wrappers

What problem does it solve?

This Skill helps you turn C FFI bindings into ABI-correct, idiomatic Nim APIs without introducing subtle bugs like wrong struct layouts, incorrect calling conventions, or unsafe ownership/lifetime handling.

Core Features & Use Cases

• Two-layer wrapper design: keep a thin raw FFI layer for ABI-faithful declarations and add an ergonomic Nim layer for safety and convenience.
• ABI and safety guardrails: preserve field order, avoid reordering, use correct calling conventions, and prevent enum modeling and memory mistakes in the raw layer.
• Ownership-aware wrappers: model move-only resources with destructor patterns, avoid fake ownership for non-handle APIs, and use exception-based error translation at clear boundaries.
• Correct C type mapping: apply consistent Nim C-interoperability types (e.g., cint, csize_t, cstring) and patterns for strings, buffers, opaque handles, and callbacks.

Quick Start

Ask the AI to generate your Nim wrapper plan by mapping the required C header elements into a minimal raw layer and a separate ergonomic layer that enforces ownership and error handling rules for your specific library.
