If your varint is < 128, it will only take a single byte to get encoded. Even if it's declared as an int64. (Also, consider that what matters isn't data size but number of frames sent.)
Anyways, if you wanted to created fixed 8- and 16-bit types, you'd have to add new field types for those, and pipe through the new types everywhere. Just grep for FIXED32 and Uint32. However you really should consider just using one of the varint-encoded types -- they will likely serve you better. -ilia On Tue, May 24, 2016 at 12:24 PM, Douglas Lewis <douglaslew...@gmail.com> wrote: > Well the solution we want to implement is with 16 bit and 8 bit elements > when that is all the resolution of the integer variable we need.
