You sort of have to roll your own. In my project I'm doing something like this:
coded_output->WriteVarint32(message->ByteSize());
message->SerializeToCodedStream(coded_output);
And then on the reading side:
uint32_t size;
if (! coded_input->ReadVarint32(&size)) {
return NULL; // just an example. probably don't want to do this;
}
Message * m = new Message;
CodedInputStream::Limit limit = coded_input->PushLimit(size);
message->ParseFromCodedStream(coded_input);
coded_input->PopLimit(limit);
The biggest thing that helped me along was finding the Limit docs. I
couldn't figure out how to parse from a ZeroCopyInputStream without
consuming the entire stream, and then I ran across that and everything
became much more clear.
