Zero-Copy Bridges Between Python and Rust: 5 Practical PyO3 Patterns Introduction In the practice of mixed programming with Python and Rust, we often encounter a crucial performance bottleneck that is frequently overlooked: the repeated copying of data when passing across language boundaries. Imagine that you have meticulously crafted a high-performance Rust function, wrapped with PyO3 … Read more
Introduction When you first rewrite Python’s performance bottlenecks in Rust, eagerly anticipating performance improvements, only to find that performance analysis shows 60% of the time wasted on hidden data copies—this experience can be both amusing and frustrating. In fact, when passing large-scale data between Python and Rust, boundary handling is more important than kernel algorithms. … Read more
Introduction Python, as a flexible and easy-to-use programming language, is loved by developers. However, when dealing with compute-intensive tasks, Python’s performance bottlenecks can often be frustrating. At this point, the Rust language, with its excellent performance and memory safety features, becomes an ideal choice for extending Python. With tools like PyO3 and maturin, we can … Read more
