structural editors for DeRon / SerRon types ?

[m172021]

Consider a type T with nested enums, structs, HashMaps, Vecs, etc ..
T implements DeRon and SerRon.

Question: can we somehow derive a "structural editor" for T within egui ?

I.e. I'd like to auto derive some structural editor in egui that "guides" the user in constructing valid values of type T, showing intermediate / error subparts in red boxes.

Thanks!
