DictSerializer (SerializerInterface)

Serialize and deserialize Dict[X, Y] into PJSONType.

Implementation: a list of tuples (key, value), because the serialized keys may not be hashable (e.g. if they're themselves serialized as a dictionary), despite the real keys being hashable.

obj_to_pjson(self, obj, type_hint)

Serialize the object to PJSON. Note that the generic self._service.to_pjson can be used here.

def obj_to_pjson(self, obj: Dict[Any, Any], type_hint: Any) -> SerializedDictType:
    key_type, value_type = get_args(type_hint)
    return [
        (self._service.to_pjson(key, key_type), self._service.to_pjson(value, value_type))
        for key, value in obj.items()
    ]

pjson_to_obj(self, pjson_obj, type_hint)

Deserialize PJSON into the object. Note that the generic self._service.from_pjson can be used here.

        for key, value in pjson_obj
