How Pydantic V2 leverages Rust's Superpowers
summary
Explains Pydantic V2’s redesign that moves most validation and serialization logic into Rust (via pydantic-core and PyO3) and presents new Pydantic V2 features. Uses examples from the Pydantic V2 codebase to show how Rust changed the library’s architecture, the performance benefits, and the trade-offs and design decisions of implementing library logic in Rust instead of Python.
