Module Fmlib_std.Array

A thin wrapper around Stdlib.Array

Use Stdlib.Array in case you need functions which are not contained in this module. There are no problems using Std.Array and Stdlib.Array, because both datatypes are identical.

type 'a t = 'a array
val length : 'a t -> int

length arr The length of the array arr.

val get : 'a t -> int -> 'a

get arr i The ith element of the array arr.

Precondition: 0 <= i && i < length [arr]

val map : ('a -> 'b) -> 'a t -> 'b t

map f arr Create a new array by mapping all elements of the original array by the function f.

val sub : 'a t -> int -> int -> 'a t

sub arr start len The subarray of arr starting at start with lenght len.

Precondition: 0 <= start && start + len <= length arr

val push : 'a -> 'a t -> 'a t

push a arr Push element a to the rear end of the array arr.

val to_list : 'a t -> 'a list

to_list arr Convert the array arr to a list with the same content.

val of_list : 'a list -> 'a array

of_list lst Convert the list lst to an array with the same content.
