pub fn intersection(a: &Btic, b: &Btic) -> Option<Btic>Expand description
Compute the intersection of two intervals.
Returns [max(a.lo, b.lo), min(a.hi, b.hi)), or None if the intervals
are disjoint (the result would be empty).
Granularity and certainty are inherited per spec ยง14.3:
- Each result bound inherits metadata from whichever input provided that bound.
- When both inputs have equal bound values, the finer granularity and least certain certainty are used.
