LanguageProject Introduction
Summary
PyO3 is a comprehensive library that provides a safe and ergonomic way to call into Python from Rust code and vice-versa. It is widely used for accelerating Python code with Rust or adding scripting capabilities to Rust applications.
Problem Solved
Bridging the gap between Rust's performance, safety, and control, and Python's extensive libraries, ease of use, and scripting environment, enabling developers to leverage the strengths of both languages in a single project.
Core Features
Building Python Extensions
Write high-performance Python modules directly in Rust, benefiting from Rust's speed and memory safety.
Embedding Python
Integrate the Python interpreter into your Rust applications to leverage Python's ecosystem and scripting capabilities.
Interoperability
Seamlessly call Python objects and functions from Rust and vice-versa, handling type conversions and the Global Interpreter Lock (GIL).

Use Cases
PyO3 is suitable for a variety of scenarios where interaction between Rust and Python is required, including:
Creating High-Performance Python Extensions
Details
Implement computationally intensive functions or libraries in Rust and expose them as standard Python modules for use in Python projects.
User Value
Achieve C-extension level performance with Rust's safety guarantees and better developer experience.
Embedding Python in Rust Applications
Details
Embed a Python interpreter within a Rust application to execute Python scripts, leverage Python libraries, or provide a plugin system.
User Value
Utilize the rich Python ecosystem (e.g., data analysis, machine learning) from a Rust codebase, or allow users to customize application behavior via Python scripts.
