type t

The type of the map keys.

val compare : t -> t -> int

A total ordering function over the keys. This is a two-argument function f such that f e1 e2 is zero if the keys e1 and e2 are equal, f e1 e2 is strictly negative if e1 is smaller than e2 , and f e1 e2 is strictly positive if e1 is greater than e2 . Example: a suitable ordering function is the generic structural comparison function compare .
