module Make (E : PARTIAL_ORD) : S with type elt = E.t
type
type
val empty : t
Empty heap
val is_empty : t -> bool
Is the heap empty?
exception Empty
val merge : t -> t -> t
Merge two heaps
val insert : elt -> t -> t
Insert a value in the heap
val add : t -> elt -> t
val filter : (elt -> bool) -> t -> t
Filter values, only retaining the ones that satisfy the predicate.
Linear time at least.
val find_min : t -> elt option
Find minimal element
val find_min_exn : t -> elt
val take : t -> (t * elt) option
Extract and return the minimum element, and the new heap (without
this element), or None if the heap is empty
val take_exn : t -> t * elt
Same as
CCHeap.S.take, but can fail.
Raises Empty if the heap is empty
val iter : (elt -> unit) -> t -> unit
Iterate on elements
val fold : ('a -> elt -> 'a) -> 'a -> t -> 'a
Fold on all values
val size : t -> int
Number of elements (linear complexity)
