invariant t checks the invariants of the queue.

val invariant : ('key, 'data) Core.Hash_queue.t -> Base.Unit.t
val create : ?growth_allowed:Base.Bool.t -> ?size:Base.Int.t -> Base.Unit.t -> (key, 'data) Core.Hash_queue.t

create () returns an empty queue. The arguments growth_allowed and size are referring to the underlying hashtable.

  • parameter growth_allowed

    defaults to true

  • parameter size

    initial size -- default to 16

val clear : ('key, 'data) Core.Hash_queue.t -> Base.Unit.t

Clears the queue.

val copy : ('key, 'data) Core.Hash_queue.t -> ('key, 'data) Core.Hash_queue.t

Makes a fresh copy of the queue with identical contents to the original.

Finding elements

val mem : ('key, 'data) Core.Hash_queue.t -> 'key -> Base.Bool.t

mem q k returns true iff there is some (k, v) in the queue.

val lookup : ('key, 'data) Core.Hash_queue.t -> 'key -> 'data Base.Option.t

lookup t k returns the value of the key-value pair in the queue with key k, if there is one.

val lookup_exn : ('key, 'data) Core.Hash_queue.t -> 'key -> 'data

Adding, removing, and replacing elements

Note that even the non-*_exn versions can raise, but only if there is an ongoing iteration.

val enqueue : ('key, 'data) Core.Hash_queue.t -> [ `back | `front ] -> 'key -> 'data -> [ `Ok | `Key_already_present ]

enqueue t back_or_front k v adds the key-value pair (k, v) to the front or back of the queue, returning `Ok if the pair was added, or `Key_already_present if there is already a (k, v') in the queue.

keys t returns the keys in the order of the queue.

val to_alist : ('key, 'data) Core.Hash_queue.t -> ('key * 'data) Base.List.t

to_alist t returns the elements of the queue with their keys in the order of the queue.

val dequeue : ('key, 'data) Core.Hash_queue.t -> [ `back | `front ] -> 'data Base.Option.t

dequeue t front_or_back returns the front or back element of the queue.

val dequeue_exn : ('key, 'data) Core.Hash_queue.t -> [ `back | `front ] -> 'data

Like dequeue, but it raises if the queue is empty.

val dequeue_back : ('key, 'data) Core.Hash_queue.t -> 'data Base.Option.t

dequeue_back t returns the back element of the queue.

val dequeue_back_exn : ('key, 'data) Core.Hash_queue.t -> 'data

Like dequeue_back, but it raises if the queue is empty.

val dequeue_front : ('key, 'data) Core.Hash_queue.t -> 'data Base.Option.t

dequeue_front t returns the front element of the queue.

val dequeue_front_exn : ('key, 'data) Core.Hash_queue.t -> 'data

Like dequeue_front, but it raises if the queue is empty.

dequeue_with_key t returns the front or back element of the queue and its key.

val dequeue_with_key_exn : ('key, 'data) Core.Hash_queue.t -> [ `back | `front ] -> 'key * 'data

Like dequeue_with_key, but it raises if the queue is empty.

val dequeue_back_with_key : ('key, 'data) Core.Hash_queue.t -> ('key * 'data) Base.Option.t

dequeue_back_with_key t returns the back element of the queue and its key.

val dequeue_back_with_key_exn : ('key, 'data) Core.Hash_queue.t -> 'key * 'data

val dequeue_all : ('key, 'data) Core.Hash_queue.t -> f:('data -> Base.Unit.t) -> Base.Unit.t

dequeue_all t ~f dequeues every element of the queue and applies f to each one. The dequeue order is from front to back.

val remove : ('key, 'data) Core.Hash_queue.t -> 'key -> [ `Ok | `No_such_key ]

replace_or_enqueue q back_or_front k v changes the value of key k in the queue to v. If the key k does not exist in the queue, it is added to the front or back with the value v.

val replace_or_enqueue_front : ('key, 'data) Core.Hash_queue.t -> 'key -> 'data -> Base.Unit.t

See replace_or_enqueue. replace_or_enqueue_front t k v is the same as replace_or_enqueue t `front k v

drop ?n q back_or_front drops n elements (default 1) from the back or front of the queue. If the queue has fewer than n elements then it is cleared.

val drop_front : ?n:Base.Int.t -> ('key, 'data) Core.Hash_queue.t -> Base.Unit.t

Equivalent to drop ?n q `front.

val drop_back : ?n:Base.Int.t -> ('key, 'data) Core.Hash_queue.t -> Base.Unit.t
