Function canMerge16

runcontainer.go:301–306

canMerge returns true iff the intervals a and b either overlap or they are contiguous and so can be merged into a single interval.

(a, b interval16)

// contiguous and so can be merged into
// a single interval.
func canMerge16(a, b interval16) bool {
	if int(a.last())+1 < int(b.start) {
		return false
	}
	return int(b.last())+1 >= int(a.start)
}

// haveOverlap differs from canMerge in that
// it tells you if the intersection of a
