Pqueue.OrderedType(3) OCaml library Pqueue.OrderedType(3) NAME Pqueue.OrderedType - Input signature of the functors Pqueue.MakeMin and Pqueue.MakeMax. Module type Module type Pqueue.OrderedType Documentation Module type OrderedType = sig end Input signature of the functors Pqueue.MakeMin and Pqueue.MakeMax . 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 . OCamldoc 2025-11-01 Pqueue.OrderedType(3)
