Binding Crate Architecture Patterns

To expose a Rust library to Python using PyO3, you create a binding crate mapping Rust types and functions to Python objects. This skill details architectural patterns, crate naming conventions, and error conversion best practices for seamless interoperability.

Best practices for mapping types and errors in FFI bindings involve translating Rust data types and error enums into equivalent host language structures. This skill covers type mapping and error conversion guidelines to ensure safe cross-language integration.

Yes, you can build native Node.js and Ruby extensions from Rust using NAPI-RS and Magnus frameworks respectively. This skill outlines specific framework patterns needed to expose Rust libraries to these host languages.

A binding crate is a specialized Rust package exposing a Rust library's functionality to a host language like Python, PHP, or Node.js. You need one when integrating high-performance Rust code into existing applications.

Common anti-patterns to avoid in Rust FFI development include improper type mapping and unsafe error conversion across the boundary. This skill identifies architectural anti-patterns to prevent robustness and safety issues in binding crates.
