Function NewGeneric

runtime/sam/expr/extent/span.go:40–49

Create a new Range from generic range of super.Values according to lower and upper. The range is not sensitive to the absolute order of lower and upper.

(lower, upper super.Value, cmp expr.CompareFn)

// to lower and upper.  The range is not sensitive to the absolute order
// of lower and upper.

		last:  upper,
		cmp:   cmp,
