May I ask what you intend to accomplish? A frequent use case for
serializing memory data is to write it to the local filesystem.
Presumably your ifstream represents a file that already exists on the
filesystem. Maybe you want to record the file's name? Perhaps you want
to record the current offset within that file? If so, I would
serialize those things specifically.
