31 A total ordering function over the keys. This is a two-argument func‐
32 tion f such that f e1 e2 is zero if the keys e1 and e2 are equal, f e1
33 e2 is strictly negative if e1 is smaller than e2 , and f e1 e2 is
34 strictly positive if e1 is greater than e2 . Example: a suitable
35 ordering function is the generic structural comparison function Perva‐
36 sives.compare .
