Function haveOverlap16

runcontainer.go:313–318

haveOverlap differs from canMerge in that it tells you if the intersection of a and b would contain an element (otherwise it would be the empty set, and we return false).

(a, b interval16)

// it would be the empty set, and we return
// false).
func haveOverlap16(a, b interval16) bool {
	if int(a.last())+1 <= int(b.start) {
		return false
	}
	return int(b.last())+1 > int(a.start)
}

// mergeInterval16s joins a and b into a
// new interval, and panics if it cannot.
