What is the primary focus of the Elixir Bindings Patterns skill?

It focuses on the architectural bridge between Elixir and Rust, specifically providing patterns for building NIFs using the Rustler library.

How does this skill handle data conversion between languages?

It implements a robust pattern using term_to_json and json_to_term helpers to safely map Elixir terms to Rust types via serde_json.

Can this skill help with performance issues in Elixir?

Yes, it provides specific guidance on using Dirty Schedulers to ensure that long-running Rust operations do not block the Erlang VM's standard schedulers.

Does it include testing patterns?

Yes, it covers the implementation of ExUnit tests within the standard Elixir project structure to verify native code behavior.

Developer Tools

Implements high-performance Elixir bindings for Rust cores using the Rustler NIF bridge pattern and OTP integration best practices.

About

This skill provides specialized architectural guidance for creating robust Elixir wrappers around Rust-based cores using the Rustler NIF (Native Implemented Function) framework. It establishes a standardized data flow between Elixir terms and Rust types via JSON serialization, manages memory safety through ResourceArc, and optimizes BEAM performance by leveraging dirty schedulers for CPU-intensive work. This is essential for developers building polyglot systems that require the high-speed processing of Rust alongside the fault tolerance and concurrency of Elixir's OTP.

Key Features

Automated resource management with ResourceArc
Comprehensive OTP integration and ExUnit testing structure
Standardized Rustler NIF bridge architecture
Safe term-to-JSON data serialization patterns
480 GitHub stars
Dirty scheduler implementation for CPU-intensive tasks

Use Cases

Wrapping high-performance Rust document parsers for use in Elixir applications
Implementing performance-critical data processing within Elixir OTP supervision trees
Developing native extensions that require safe memory management and GC integration
