Author of typedload here. typedload does this without need to pass a "discriminator" parameter. Just having the types with the same field defined as a literal of different things will suffice. I've also implemented an algorithm to inspect the data and find out the type directly from the literal field, to avoid having to try multiple types when loading a union. Pydantic has also implemented the same strategy afterwards. typedload is faster than pydantic to load tagged unions. It is written in pure python. edit: Also, typedload just uses completely regular dataclasses or attrs. No need for all those different BaseModel, RootModel and understanding when to use them.
