pub enum FlatSet<T> {
    Bottom,
    Elem(T),
    Top,
}
Expand description

Extends a type T with top and bottom elements to make it a partially ordered set in which no value of T is comparable with any other.

A flat set has the following Hasse diagram:

         top
 / ... / /  \ \ ... \
all possible values of `T`
 \ ... \ \  / / ... /
        bottom
