Then, if you are using C++, you use that code like this: Person person; person.set_id(123); person.set_name("Bob"); person.set_email("bob@example.com"); fstream out("person.pb", ios::out | ios::binary | ios::trunc); person.SerializeToOstream(&out); out.close(); Or like this: Person person; fstream in("person.pb", ios::in | ios::binary); if (!person.ParseFromIstream(&in)) { cerr
