Immutable Arrays

Purely functional use of arrays. Update is costly, but reads are very fast. Sadly, it is not possible to make this type covariant without using black magic.
Since 0.17


type 'a t 
Array of values of type 'a. The underlying type really is an array, but it will never be modified.

It should be covariant but OCaml will not accept it.

val empty : 'a t
val length : 'a t -> int
val singleton : 'a -> 'a t
val doubleton : 'a -> 'a -> 'a t
val make : int -> 'a -> 'a t
make n x makes an array of n times x
val init : int -> (int -> 'a) -> 'a t
init n f makes the array [| f 0; f 1; ... ; f (n-1) |].
Raises Invalid_argument if n < 0
val get : 'a t -> int -> 'a
Access the element
val set : 'a t -> int -> 'a -> 'a t
Copy the array and modify its copy
val map : ('a -> 'b) -> 'a t -> 'b t
val mapi : (int -> 'a -> 'b) -> 'a t -> 'b t
val append : 'a t -> 'a t -> 'a t
val iter : ('a -> unit) -> 'a t -> unit
val iteri : (int -> 'a -> unit) -> 'a t -> unit
val foldi : ('a -> int -> 'b -> 'a) -> 'a -> 'b t -> 'a
val fold : ('a -> 'b -> 'a) -> 'a -> 'b t -> 'a
val for_all : ('a -> bool) -> 'a t -> bool
val exists : ('a -> bool) -> 'a t -> bool

Conversions


type 'a sequence = ('a -> unit) -> unit 
type 'a gen = unit -> 'a option 
val of_list : 'a list -> 'a t
val to_list : 'a t -> 'a list
val of_array_unsafe : 'a array -> 'a t
Take ownership of the given array. Careful, the array must NOT be modified afterwards!
val to_seq : 'a t -> 'a sequence
val of_seq : 'a sequence -> 'a t
val of_gen : 'a gen -> 'a t
val to_gen : 'a t -> 'a gen

IO


type 'a printer = Format.formatter -> 'a -> unit 
val print : ?start:string ->
?stop:string ->
?sep:string ->
'a printer -> 'a t printer
