devel/py-pydantic-compat 0.1.2p2 OpenBSD

This package provides (unofficial) compatibility mixins and function adaptors for pydantic v1-v2 cross compatibility. It allows you to use either v1 or v2 API names, regardless of the pydantic version installed. (Prefer using v2 names when possible).

Pydantic 2 was a major release that completely changed the pydantic API.

For applications, this is not a big deal, as they can pin to whatever version of pydantic they need. But for libraries that want to exist in a broader environment, pinning to a specific version of pydantic is not always an option (as it limits the ability to co-exist with other libraries).
