/*
Instead of using enum it's possible to use RawRepresentable struct that will give you support for "unsupported" values,
but will cost you excastive switches (you'll alwyas have to handle default case, which will stand for those "unsupported" values)
It's defenetely more code than if using optional, but might be better if it comes to unwrapping this value everywhere.
