Enum Relation 

pub enum Relation {
    Precedes {
        is_inverted: bool,
    },
    Meets {
        is_inverted: bool,
    },
    Overlaps {
        is_inverted: bool,
    },
    Finishes {
        is_inverted: bool,
    },
    Contains {
        is_inverted: bool,
    },
    Starts {
        is_inverted: bool,
    },
    Equals,
}

A type describing the possible relations between two intervals (e.g. s and t).

The relations are comparable (via Ord) by the degree to which s begins before t and then within that by the degree to which s ends before t.

Six pairs of the relations are converses. For example, the converse of “s precedes t” is “t is preceded by s”; whenever the first relation is true, its converse is true also. The thirteenth, “s equals t”, is its own converse
