Description

Currently, there is only one package that can be used for validation and (de)-serialization. Having the possibility to choose one's validator library would strenghten the micro-framework part of FastAPI and bolster faster and innovative projects (I'm thinking of apischema, but there could be others). Currently, the approach of having to build another framework such as Flama to simply be able to use another validator does not make sense to me.

The solution you would like

Have an interface in FastAPI for the validation / deser so that external (non-default) validators such as marshmallow, apischema, etc. could be plugged in.

We would be very interested in this as we use apischema a lot. @tiangolo does this align with your goals for FastAPI? Would you accept a PR adding a plugin mechanism for external validators?

We would also be interested in this, especially the ability to integrate with apischema.

My own performance testing between typedload, apischema and pydantic looks like this: https://ltworf.github.io/typedload/performance.html
