Support Explicit JSON null

[rise0chen]

Failed to deserialize when google::protobuf::*Value is null

[rise0chen]

I can't impl Deserialize for Optiongoogle::protobuf::*Value

[tustvold]

I'm not sure I understand the problem? Could you perhaps provide an example of some JSON that behaves incorrectly?

[rise0chen]

message KitchenSink {
  google.protobuf.UInt64Value uint64_value = 56;
}

{"uint64Value": null}

[tustvold]

Does this work?

message Other {}

message KitchenSink {
    Other other = 1;
}

{"other": null}

I'm not seeing why UInt64Value would be any different from a normal message, and wonder if there is a more general issue here with how we handle nulls when deserializing?

[rise0chen]

not work

[tustvold]

Ok I'll have a play, I have some ideas of what is going on
