Implementations

impl RangeIntersect

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

Test two inclusive ranges for intersection, returning None if the ranges are disjoint.

assert_eq!(
  RangeIntersect::compare (&(0..=5), &(0..=5)),
  Some (RangeIntersect::EqualTo));
