class_docstr: Abstract base class for protocol messages.
  
  Protocol message classes are almost always generated by the protocol
  compiler.  These generated types subclass Message and implement the methods
  shown below.
docstr: Copies the content of the specified message into the current message.
  
  The method clears the current message and then merges the specified
  message using MergeFrom.
  
  Args:
    other_msg (Message): A message to copy into the current one.
