module type OrderedType = sig .. endInput signature of the functor MoreLabels.Set.Make.
type t
The type of the set elements.
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 compare.
