LanguageProject Introduction
Summary
PyO3 enables developers to write native Python extension modules in Rust or embed the Python interpreter in a Rust application. It offers a high-level API to interact with Python objects, manage the GIL, and handle type conversions, making it a powerful tool for performance-critical Python code or accessing Python libraries from Rust.
Problem Solved
Combining the performance of Rust with the extensive ecosystem and ease of use of Python can be challenging. PyO3 solves this by providing a robust and safe bridge, allowing developers to leverage the strengths of both languages within a single project.
Core Features
Calling Rust from Python
Easily call Rust functions, methods, and objects from Python.
Calling Python from Rust
Execute Python code, import modules, and interact with Python objects from Rust.
Type Conversion
Automatic conversion between common Python and Rust types, reducing boilerplate.
GIL Management
Provides safe abstractions for managing the Python Global Interpreter Lock (GIL).
