Enum KeyPosition 

pub enum KeyPosition<K> {
    Start,
    At(K),
    End,
}

A position between windows of an ordered key space. No minimum key or successor operation is required.

Variants

Start

No keys have been visited.

At(K)

The inclusive lower bound on keys still to visit.

End

All keys have been visited.
