Note that the second shift - the (n >> 31) part - is an arithmetic shift. Basically I have some other services that only depend on the partial message, so I'm just extracting the serialized sub-message and forwarding it to them without having to go through the whole deserialize/serialize process again. For those familiar with the details, we are using coeffcients a=2.4 and b=1.05. Conclusion. Add the streaming support to the proto file. The code generated by this compiler is based on the optimized code generated by gogo/protobuf, although this package is not a fork of the original gogo compiler, as it has been implemented to support .
