Module `Base.Uniform_array`

Same semantics as 'a Array.t, except it's guaranteed that the representation array is not tagged with Double_array_tag, the tag for float arrays.

This means it's safer to use in the presence of Obj.magic, but it's slower than normal Array if you use it with floats.

It can often be faster than Array if you use it with non-floats.

type 'a t: See Base.Array for comments.

include Sexpable.S1 with type 'a t := 'a t

type 'a t

val t_of_sexp : (Sexplib0.Sexp.t -> 'a) -> Sexplib0.Sexp.t -> 'a t
val sexp_of_t : ('a -> Sexplib0.Sexp.t) -> 'a t -> Sexplib0.Sexp.t

val invariant : _ t -> unit
val empty : _ t
val create : len:int -> 'a -> 'a t
val singleton : 'a -> 'a t
val init : int -> f:(int -> 'a) -> 'a t
val length : 'a t -> int
val get : 'a t -> int -> 'a
val unsafe_get : 'a t -> int -> 'a
val set : 'a t -> int -> 'a -> unit
val unsafe_set : 'a t -> int -> 'a -> unit
val swap : _ t -> int -> int -> unit
val unsafe_set_omit_phys_equal_check : 'a t -> int -> 'a -> unit: unsafe_set_omit_phys_equal_check is like unsafe_set, except it doesn't do a phys_equal check to try to skip caml_modify. It is safe to call this even if the values are phys_equal.

val map : 'a t -> f:('a -> 'b) -> 'b t
val iter : 'a t -> f:('a -> unit) -> unit
val iteri : 'a t -> f:(int -> 'a -> unit) -> unit: Like iter, but the function is applied to the index of the element as first argument, and the element itself as second argument.

val of_array : 'a array -> 'a t: of_array and to_array return fresh arrays with the same contents rather than returning a reference to the underlying array.

val to_array : 'a t -> 'a array
val of_list : 'a list -> 'a t
val to_list : 'a t -> 'a list

include Blit.S1 with type 'a t := 'a t

type 'a t

val blit : ('a t, 'a t) Base__.Blit_intf.blit
val blito : ('a t, 'a t) Base__.Blit_intf.blito
val unsafe_blit : ('a t, 'a t) Base__.Blit_intf.blit
val sub : ('a t, 'a t) Base__.Blit_intf.sub
val subo : ('a t, 'a t) Base__.Blit_intf.subo

val copy : 'a t -> 'a t

Extra lowlevel and unsafe functions

val unsafe_create_uninitialized : len:int -> _ t: The behavior is undefined if you access an element before setting it.

val create_obj_array : len:int -> Base__.Import.Caml.Obj.t t: New obj array filled with Obj.repr 0

val unsafe_set_assuming_currently_int : Base__.Import.Caml.Obj.t t -> int -> Base__.Import.Caml.Obj.t -> unit

unsafe_set_assuming_currently_int t i obj sets index i of t to obj, but only works correctly if the value there is an immediate, i.e. Caml.Obj.is_int (get t i). This precondition saves a dynamic check.

unsafe_set_int_assuming_currently_int is similar, except the value being set is an int.

unsafe_set_int is similar but does not assume anything about the target.

val unsafe_set_int_assuming_currently_int : Base__.Import.Caml.Obj.t t -> int -> int -> unit
val unsafe_set_int : Base__.Import.Caml.Obj.t t -> int -> int -> unit
val unsafe_clear_if_pointer : Base__.Import.Caml.Obj.t t -> int -> unit: unsafe_clear_if_pointer t i prevents t.(i) from pointing to anything to prevent space leaks. It does this by setting t.(i) to Caml.Obj.repr 0. As a performance hack, it only does this when not (Caml.Obj.is_int t.(i)). It is an error to access the cleared index before setting it again.

val exists : 'a t -> f:('a -> bool) -> bool: As Array.exists.

val map2_exn : 'a t -> 'b t -> f:('a -> 'b -> 'c) -> 'c t: Functions with the 2 suffix raise an exception if the lengths of the two given arrays aren't the same.

val min_elt : 'a t -> compare:('a -> 'a -> int) -> 'a option
val max_elt : 'a t -> compare:('a -> 'a -> int) -> 'a option
