Module type Map.OrderedType

module type OrderedType = sig .. end

Input signature of the functor Map.Make.


type t;

The type of the map keys.

let 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.
