To me it sounds like Qt needs a new lower-level class for serializing and deserializing stuff.

QDataStream is for Qt only, it’s incompatible with all other binary formats out there, with the undocumented exception for cases where primitive types match.

I would recommend against using QDataStream for anything else than reading back what was written using QDataStream.
