Methods

impl RangeDisjoint

pub fn compare<T: PrimInt>(
    left: &RangeInclusive<T>,
    right: &RangeInclusive<T>
) -> Option<Self>

Tests two inclusive ranges for disjointness, returning None if they intersect.

assert_eq!(RangeDisjoint::compare (&(0..=5), &(0..=5)), None);
assert_eq!(
  RangeDisjoint::compare (&(1..=0), &(1..=0)),
  Some (RangeDisjoint::EmptyBoth));
assert_eq!(
  RangeDisjoint::compare (&(1..=0), &(0..=5)),
  Some (RangeDisjoint::EmptyLhs));
assert_eq!(
  RangeDisjoint::compare (&(0..=5), &(1..=0)),
  Some (RangeDisjoint::EmptyRhs));
assert_eq!(
  RangeDisjoint::compare (&(0..=2), &(4..=5)),
  Some (RangeDisjoint::LessThanProper));
assert_eq!(
  RangeDisjoint::compare (&(0..=2), &(3..=5)),
  Some (RangeDisjoint::LessThanAdjacent));
assert_eq!(
  RangeDisjoint::compare (&(4..=5), &(0..=2)),
  Some (RangeDisjoint::GreaterThanProper));
assert_eq!(
  RangeDisjoint::compare (&(3..=5), &(0..=2)),
