type t

The type of the set elements.

include Set.OrderedType with type t := t
val compare : t -> t -> int

A total ordering function over the set elements. This is a two-argument function f such that f e1 e2 is zero if the elements 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

val zero : t

The zeroth element

val pred : t -> t

Predecessor of an element

val succ : t -> t

Successor of an element

val sub : t -> t -> t

sub a b returns a - b

val add : t -> t -> t

add a b returns a + b

val to_string : t -> string

Display an element.
