Hi, Kenton,
The main problem is how can I serialize two different objects into one
stream.
e.g. If I serialize the Text object into one file, how can I append
another object Image into the file.
Also the methods how to deserialize? Thanks.
I found the method Message.AppendToString(string* out), but I did
not find the matched deserialize method.
