PyO3 and Rust in Action: Migrating Pascal to Rust for Python Integration

Explore a presentation from the Rust Zürisee meetup in Switzerland, focusing on Gerhard Bräunlich's experience migrating Pascal code to a Rust module for use in Python. Learn how Rust improved Python and C code in an LCA software by Sustainable System Solutions, preventing segfaults while maintaining C-like performance. Discover the process of integrating Rust with Python using PyO3, including code examples, benchmarking, and optimization techniques. Gain insights into custom Python types, the advantages of Rust in scientific computing, and the speaker's impressions of PyO3. Delve into topics such as just-in-time compilers and the future of Python in scientific applications.
