You can simply reflect on your nested structs and generate the 
enum from them. No need to duplicate anything.

The only thing you have to do is figure out how to determine if a 
nested struct is part of the enum. If all nested structs of Layer 
are then it is easy. Else some naming scheme or inheritance needs 
to be used to distinguish them from others.
