type t
The type of elements.
val compare : t -> t -> int
A total ordering function to compare 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 .
The generic structural comparison function compare is a suitable ordering function for element types such as int or string .
