pydantic_core is the Rust-based core validation engine that powers Pydantic; its own package is not separately described on the fetched pages, but Pydantic's stack page 1 presents the Pydantic ecosystem for type-safe Python data handling, and the 'pydantic' action record describes Pydantic as a Python data validation and serialization library based on type hints 1. For direct validation and serialization built on the same core, Pydantic itself is the closest match, with Mashumaro offering ty
