R wrapper for the ZeroCopyOutputStream c++ class

classes

Protocol Buffers are a way of encoding structured data in an
efficient yet extensible format. Google uses Protocol Buffers for almost all
of its internal 'RPC' protocols and file formats. Additional documentation
is available in two included vignettes one of which corresponds to our 'JSS'
paper (2016, <doi:10.18637/jss.v071.i02>. Either version 2 or 3 of the
'Protocol Buffers' 'API' is supported.
