val iter_keys : _ t -> f:(Key.t -> unit) -> unit

Mutation of the heap during iteration is not supported, but there is no check to prevent it. The behavior of a heap that is mutated during iteration is undefined.

val iter : 'a t -> f:('a -> unit) -> unit
val iteri : 'a t -> f:(key:Key.t -> data:'a -> unit) -> unit
val to_alist : 'a t -> (Key.t * 'a) list

Returns the list of all (key, value) pairs for given Hash_heap.

val length : 'a t -> int
val is_empty : 'a t -> bool
val clear : 'a t -> unit

Removes all values, leaving the hash heap empty. *
