Module Core.Option_arraySource

This module extends Base.Option_array with bin_io.

These are all like their equivalents in Container except that an index starting at 0 is added as the first argument to f.

Sourceval of_array_some : 'a array -> 'a t
Sourceval to_array : 'a t -> 'a option Base.Array.t
Sourceval get : 'a t -> int -> 'a option

get t i returns the element number i of array t, raising if i is outside the range 0 to length t - 1.

Sourceval get_local : 'a t -> int -> 'a option

Similar to get, but allocates result in the caller's stack region instead of heap.

Sourceval get_some_exn : 'a t -> int -> 'a

Raises if the element number i is None.

Sourceval is_none : _ t -> int -> bool

is_none t i = Option.is_none (get t i)

Sourceval is_some : _ t -> int -> bool

is_some t i = Option.is_some (get t i)

These can cause arbitrary behavior when used for an out-of-bounds array access.

Sourceval unsafe_get : 'a t -> int -> 'a option
Sourceval unsafe_get_some_exn : 'a t -> int -> 'a

unsafe_get_some_exn t i is unsafe because it does not bounds check i. It does, however check whether the value at index i is none or some, and raises if it is none.

Sourceval unsafe_get_some_assuming_some : 'a t -> int -> 'a

unsafe_get_some_assuming_some t i is unsafe both because it does not bounds check i and because it does not check whether the value at index i is none or some, assuming that it is some.

Sourceval unsafe_is_some : _ t -> int -> bool
Sourceval set : 'a t -> int -> 'a option -> unit

set t i x modifies array t in place, replacing element number i with x, raising if i is outside the range 0 to length t - 1.

Sourceval set_some : 'a t -> int -> 'a -> unit
Sourceval set_none : _ t -> int -> unit
Sourceval swap : _ t -> int -> int -> unit
Sourceval clear : _ t -> unit

Replaces all the elements of the array with None.

Sourceval map : 'a t -> f:('a option -> 'b option) -> 'b t

map f [|a1; ...; an|] applies function f to a1, a2, ..., an, in order, and builds the option_array [|f a1; ...; f an|] with the results returned by f.

Sourceval map_some : 'a t -> f:('a -> 'b) -> 'b t

map_some t ~f is like map, but None elements always map to None and Some always map to Some.

Unsafe versions of set*. Can cause arbitrary behaviour when used for an out-of-bounds array access.

Sourceval sub : 'a t -> pos:int -> len:int -> 'a t
Sourceval subo : ?pos:int -> ?len:int -> 'a t -> 'a t
Sourceval copy : 'a t -> 'a t

Makes a (shallow) copy of the array.
