pyo3-performance-patterns

What problem does it solve?

This Skill addresses performance bottlenecks when integrating asynchronous Rust code with Python, particularly concerning GIL management and efficient callback handling.

Core Features & Use Cases

• Async Callback Optimization: Leverages pyo3_async_runtimes for significantly faster async Python callbacks compared to spawn_blocking.
• GIL Management: Provides patterns for releasing the GIL before awaiting async operations and using Python::attach() appropriately.
• Use Case: When calling a Rust function from Python that involves asynchronous operations, this Skill ensures the most performant and deadlock-free execution path is chosen based on whether the operation is quick or long-running.

Quick Start

Use the pyo3-performance-patterns skill to optimize an async Python callback by releasing the GIL before awaiting.
