(De)serialization to other types

I’d love for Marshmallow to be more modular, for example I’m loading from JSON and serializing to bencode. It would be great if there was a simple way to do this.

It was suggested in https://github.com/marshmallow-code/marshmallow/issues/130 but the solution assumes that the source and destination encoding are the same.

Ah, I see. OK, for now I’d recommend implementing a custom render class that implements dumps and loads.

class ComboRenderer:
    @staticmethod
    def loads(s, *args, **kwargs):
        return json.loads(s, *args, **kwargs)

    @staticmethod
    def dumps(obj, *args, **kwargs):
        return yaml.dumps(obj, *args, **kwargs)


class MySchema(Schema):
    class Meta:
        render_module = ComboRenderer

I was about to close this as this is a corner case and the two-schema solution seems reasonable enough.

OTOH, this would be really easy to achieve, all it takes is a load_render_module and a dump_render_module rather than just render_module.
