Room for more fields?
Yep, future fields. "Tag numbers 1-15 require one less byte to encode than higher numbers, so as an optimization you can decide to use those tags for the commonly used or repeated elements, leaving tags 16 and higher for less-commonly used optional elements. Each element in a repeated field requires re-encoding the tag number, so repeated fields are particularly good candidates for this optimization." https://developers.google.com/protocol-buffers/docs/cpptutorial?hl=en - Alexander ----------------------------------------------------------- This is an automatically generated e-mail.
