This is intended behavior, but there should be a cleaner error. Unit structs and enums are currently not supported by the macro, but implementing reactive state manually is usually not too tricky (and all documented). In your case, I would recommend moving the type into a field so you can use the macro as usual.

The ReactiveState macro will be expanded further after v0.4.0 goes stable I think.
