pandera.dtypes.immutable(pandera_dtype_cls=None, **dataclass_kwargs)

dataclasses.dataclass() decorator with different default values: frozen=True, init=False, repr=False.

• dataclass_kwargs (Any) – Keywords arguments forwarded to dataclasses.dataclass().

Return type:

Union[Type[~_Dtype], Callable[[Type[~_Dtype]], Type[~_Dtype]]]
