include Container.S1 with type 'a t := 'a t
val mem : 'a t -> 'a -> equal:( 'a -> 'a -> bool ) -> bool
Checks whether the provided element is there, using equal
.
val length : 'a t -> int
val is_empty : 'a t -> bool
val iter : 'a t -> f:( 'a -> unit ) -> unit
val fold : 'a t -> init:'accum -> f:( 'accum -> 'a -> 'accum ) -> 'accum
fold t ~init ~f
returns f (... f (f (f init e1) e2) e3 ...) en
, where e1..en
are the elements of t
val fold_result :
'a t ->
init:'accum ->
f:( 'accum -> 'a -> ( 'accum, 'e ) Result.t ) ->
( 'accum, 'e ) Result.t
fold_result t ~init ~f
is a short-circuiting version of fold
that runs in the Result
monad. If f
returns an Error _
, that value is returned without any additional invocations of f
.
val fold_until :
'a t ->
init:'accum ->
f:
( 'accum ->
'a ->
( 'accum, 'final ) Base__Container_intf.Export.Continue_or_stop.t ) ->
finish:( 'accum -> 'final ) ->
'final
fold_until t ~init ~f ~finish
is a short-circuiting version of fold
. If f
returns Stop _
the computation ceases and results in that value. If f
returns Continue _
, the fold will proceed. If f
never returns Stop _
, the final result is computed by finish
.
Example:
type maybe_negative =
| Found_negative of int
| All_nonnegative of { sum : int }
(** [first_neg_or_sum list] returns the first negative number in [list], if any,
otherwise returns the sum of the list. *)
let first_neg_or_sum =
List.fold_until ~init:0
~f:(fun sum x ->
if x < 0
then Stop (Found_negative x)
else Continue (sum + x))
~finish:(fun sum -> All_nonnegative { sum })
;;
let x = first_neg_or_sum [1; 2; 3; 4; 5]
val x : maybe_negative = All_nonnegative {sum = 15}
let y = first_neg_or_sum [1; 2; -3; 4; 5]
val y : maybe_negative = Found_negative -3
val exists : 'a t -> f:( 'a -> bool ) -> bool
Returns true
if and only if there exists an element for which the provided function evaluates to true
. This is a short-circuiting operation.
val for_all : 'a t -> f:( 'a -> bool ) -> bool
Returns true
if and only if the provided function evaluates to true
for all elements. This is a short-circuiting operation.
val count : 'a t -> f:( 'a -> bool ) -> int
Returns the number of elements for which the provided function evaluates to true.
val sum :
(module Base__Container_intf.Summable with type t = 'sum) ->
'a t ->
f:( 'a -> 'sum ) ->
'sum
Returns the sum of f i
for all i
in the container.
val find : 'a t -> f:( 'a -> bool ) -> 'a option
Returns as an option
the first element for which f
evaluates to true.
val find_map : 'a t -> f:( 'a -> 'b option ) -> 'b option
Returns the first evaluation of f
that returns Some
, and returns None
if there is no such element.
val to_list : 'a t -> 'a list
val to_array : 'a t -> 'a array
val min_elt : 'a t -> compare:( 'a -> 'a -> int ) -> 'a option
Returns a minimum (resp maximum) element from the collection using the provided compare
function, or None
if the collection is empty. In case of a tie, the first element encountered while traversing the collection is returned. The implementation uses fold
so it has the same complexity as fold
.
val max_elt : 'a t -> compare:( 'a -> 'a -> int ) -> 'a option
These are all like their equivalents in Container
except that an index starting at 0 is added as the first argument to f
.
val foldi : 'a t -> init:_ -> f:( int -> _ -> 'a -> _ ) -> _
val iteri : 'a t -> f:( int -> 'a -> unit ) -> unit
val existsi : 'a t -> f:( int -> 'a -> bool ) -> bool
val for_alli : 'a t -> f:( int -> 'a -> bool ) -> bool
val counti : 'a t -> f:( int -> 'a -> bool ) -> int
val findi : 'a t -> f:( int -> 'a -> bool ) -> (int * 'a) option
val find_mapi : 'a t -> f:( int -> 'a -> 'b option ) -> 'b option
val singleton : 'a -> 'a t
singleton a
returns a queue with one element.
val of_list : 'a list -> 'a t
of_list list
returns a queue t
with the elements of list
in the same order as the elements of list
(i.e. the first element of t
is the first element of the list).
val of_array : 'a array -> 'a t
val init : int -> f:( int -> 'a ) -> 'a t
init n ~f
is equivalent to of_list (List.init n ~f)
.
val enqueue : 'a t -> 'a -> unit
enqueue t a
adds a
to the end of t
.
val enqueue_all : 'a t -> 'a list -> unit
enqueue_all t list
adds all elements in list
to t
in order of list
.
val dequeue : 'a t -> 'a option
dequeue t
removes and returns the front element of t
, if any.
val dequeue_exn : 'a t -> 'a
val peek : 'a t -> 'a option
peek t
returns but does not remove the front element of t
, if any.
val peek_exn : 'a t -> 'a
val clear : _ t -> unit
clear t
discards all elements from t
.
Creates a new queue with elements equal to List.concat_map ~f (to_list t)
.
filter_map
creates a new queue with elements equal to List.filter_map ~f (to_list
t)
.
val filter_inplace : 'a t -> f:( 'a -> bool ) -> unit
filter_inplace t ~f
removes all elements of t
that don't satisfy f
. If f
raises, t
is unchanged. This is inplace in that it modifies t
; however, it uses space linear in the final length of t
.
val filteri_inplace : 'a t -> f:( int -> 'a -> bool ) -> unit
val create : unit -> _ t
create ()
returns an empty queue.
