Custom options support

[upcFrost]

Hi,

Does proto-plus support custom options? Especially FieldOptions, like this one

extend google.protobuf.FieldOptions {
  optional uint32 some_option = 50002;
}
message MyMessage {
  string id = 1 [(some_option) = 10];
}

In vanilla protobuf these options are available as proto_pb2.MyMessage.id.DESCRIPTOR.GetOptions().Extensions[proto_pb2.some_option], but I don't see them anywhere in proto-plus, neither in the proto.Field model description nor in the descriptor made with pb().

Best regards,
Petr

Case: I want to log requests and responses. Logging tokens and passwords is not exactly good. Keeping a huge dict what to log and what to skip is prone to errors. The best solution, imo, is to create an option like do_not_log and set it on the field. Then I can add custom logic on the logger to take field options into account. With this just by looking at the proto file I can tell which data is sensitive and should not be logged.

Another case: I want to add value checks on the field. For example, to have min and max values for integers. Adding it per-method is, again, prone to errors, and it's hard to tell why did the service reject the request w/o looking at the code. Having all those rules inside a proto file will make it much easier assess which conditions are set for each value

anyone?

Agreed that this is an important capability to support.
