Dictionary representation improvement?

Is there a better way to represent this dictionary into a Struct()? (Currently using 2.0.0b3)

capability_dict = {"@context": "https://w3id.org/security/v2",
			  "target": "urn:trinsic:wallets:noop",
			  "proof": {
				  "created": datetime.datetime.now()
			  }
			  }

The following does work, but seems pretty kludgy:

proof = Struct()
proof.fields["created"] = Value(string_value=str(datetime.datetime.now()))
capability = Struct()
capability.fields["@context"] = Value(string_value="https://w3id.org/security/v2")
capability.fields["target"] = Value(string_value="urn:trinsic:wallets:noop")
capability.fields["proof"] = Value(struct_value=proof)

• It seems to me that we could/should at least have a Struct.from_dictionary(obj: dict) method. I'd be happy to write this if it doesn't exist.
• Struct.from_dict() does NOT work for this, tested.

Example code of what I'm thinking:

def value_to_proto_value(obj: Any) -> Value:
    value = Value()
    if isinstance(obj, str) or isinstance(obj, datetime.datetime):
        value = Value(string_value=str(obj))
    elif isinstance(obj, int) or isinstance(obj, float):
        value = Value(number_value=float(obj))
    elif isinstance(obj, bool):
        value = Value(bool_value=obj)
    elif isinstance(obj, dict):
        value = Value(struct_value=dictionary_to_struct(obj))
    elif isinstance(obj, list):
        value = Value(list_value=list_to_proto_list(obj))

    return value


def list_to_proto_list(obj: List) -> ListValue:
    return ListValue(values=[value_to_proto_value(item) for item in obj])


def dictionary_to_struct(obj: Dict[str, Any]) -> Struct:
    return Struct(fields=dict([(k, value_to_proto_value(v)) for k, v in obj.items()]))

Commencez par localiser les définitions de Struct, Value et ListValue et examinez pourquoi Struct.from_dict() ne gère pas le dictionnaire imbriqué présenté. Confirmez le comportement de conversion prévu pour les dictionnaires imbriqués, les listes, les chaînes, les nombres, les booléens et les valeurs datetime. Le travail est considéré comme terminé lorsqu’une API ergonomique est définie d’un commun accord et que la représentation d’exemple est couverte.
