pub enum RangeRelation<T> {
    Before(T),
    Overlap(T),
    After(T),
    Last(T),
    Invalid(T),
}

This enum is used to represent positional relationships between 2 ranges.

• before a range: RangeRelation::Before
• overlap with a range: RangeRelation::Overlap
• after a range: RangeRelation::Overlap

The additional states, represent the initialization of the set.

• empty or no data: RangeRelation::Invalid
• last or final: RangeRelation::Last

Variants

Range a is before range b

Overlap(T)

Range a and b overlap

After(T)

Range a is after range b

Last(T)

Represents final set of data

Invalid(T)

Denotes a was not valid
