A representation of the Spanner PROTO type: a protobuf message.
A ProtoMessage<M> can be implicitly constructed from and explicitly converted to an M. Values can be copied, assigned, and streamed.
A ProtoMessage<M> can also be explicitly constructed from and converted to the M wire format, although this is intended for internal use only.
Example
Given a proto definition message Mesg { string field = 1; }:
Mesg m;
m.set_field("value");
auto pm = spanner::ProtoMessage<Mesg>(m);
assert(Mesg(pm).field() == "value");
