Struct Unselected 

pub struct Unselected;

The default “no option selected” variant, shared by every ExclusiveOption group.

It is a zero-sized type whose ExclusiveOption::inject_args is a no-op, so any mutually exclusive option group can use it as its default type parameter instead of defining its own empty variant.
