Hi I have done now some research: singular seem to be fields, that have no addition field rules (like optional, repeated, map). There is no presence indication.
BUT: The docu says: "a well-formed message can have zero or one of this field (but not more than one)" What does that mean? Are this wrapper messages with 1 field meant? https://github.com/protocolbuffers/protobuf/blob/main/src/google/protobuf/wrappers.proto Thanks a lot Michael -- You received this message because you are subscribed to the Google Groups "Protocol Buffers" group.
