Annotates a class as a DocArray dataclass type.

Example usage:

>>> from docarray.typing import Image, Text
>>> from docarray import dataclass
>>> @dataclass:
>>> class X:
>>>     banner: Image = 'apple.png'
>>>     description: Text = 'This is a big red apple.'

type_var_map (Optional[Dict[TypeVar, Callable[[ForwardRef], ForwardRef]]]) –

a mapping from TypeVar to a callable that gives Field.

    Image: lambda x: field(setter=image_setter, getter=image_getter, _source_field=x),
    Text: lambda x: field(setter=text_setter, getter=text_getter, _source_field=x),

The default mapping will be overrided by this new mapping if they collide on the keys.

Return type



Returns True if obj is an instance of dataclass().
