Well, not really, of course. All of this will make sense once we start adding support for fields and non-struct types. Refactoring the code now before we start to add actual member field parsing is much easier. How do I know that this will work out? Well, my crystal ball knows it. Don't believe me? Okay, ChatGPT told me ... Alright alright, I went through the entire process of implementing this feature *twice* at this point and have a pretty good idea of where to draw the abstraction lines so that everything falls neatly into place. You'll have to trust me on this one. (Or, you know, check out old branches in my xmpp-rs repo. That might work, too. `feature/derive-macro-streaming-full` might be a name to look for if you dare.)
