Module Core_kernel.Uniform_array

This module extends Base.Uniform_array with bin_io.

type 'a t = 'a Base.Uniform_array.t
include Bin_prot.Binable.S1 with type 'a t := 'a t
val bin_shape_t : Bin_prot.Shape.t -> Bin_prot.Shape.t
val bin_size_t : ('a, 'a t) Bin_prot.Size.sizer1
val bin_write_t : ('a, 'a t) Bin_prot.Write.writer1
val bin_read_t : ('a, 'a t) Bin_prot.Read.reader1
val __bin_read_t__ : ('a, int -> 'a t) Bin_prot.Read.reader1
val bin_writer_t : ('a, 'a t) Bin_prot.Type_class.S1.writer
val bin_reader_t : ('a, 'a t) Bin_prot.Type_class.S1.reader
val bin_t : ('a, 'a t) Bin_prot.Type_class.S1.t
include Ppx_sexp_conv_lib.Sexpable.S1 with type 'a t := '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
include module type of sig ... end with type 'a Uniform_array.t := 'a t

include Base.Sexpable.S1 with type 'a t := '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 : 'a t -> unit
val empty : 'a 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 : 'a 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) -> 'a 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 Base.Blit.S1 with type 'a t := 'a t
val blit : src:'a t -> src_pos:int -> dst:'a t -> dst_pos:int -> len:int -> unit
val blito : src:'a t -> ?⁠src_pos:int -> ?⁠src_len:int -> dst:'a t -> ?⁠dst_pos:int -> unit -> unit
val unsafe_blit : src:'a t -> src_pos:int -> dst:'a t -> dst_pos:int -> len:int -> unit
val sub : 'a t -> pos:int -> len:int -> 'a t
val subo : ?⁠pos:int -> ?⁠len:int -> 'a t -> 'a t
val copy : 'a t -> 'a t

Extra lowlevel and unsafe functions

val unsafe_create_uninitialized : len:int -> 'a t

The behavior is undefined if you access an element before setting it.

val create_obj_array : len:int -> 'a t

New obj array filled with Obj.repr 0

val unsafe_set_assuming_currently_int : 'a t -> int -> 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 : 'a t -> int -> int -> unit
val unsafe_set_int : 'a t -> int -> int -> unit
val unsafe_clear_if_pointer : 'a 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 -> 'a t -> f:('a -> 'b -> 'c) -> 'a 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
