(** Unsafe IO. (See {!Deriving_Json} for typesafe IO) *)

val output : 'a -> Js.js_string Js.t
(** Marshal any OCaml value into this JSON representation. *)

val unsafe_input : Js.js_string Js.t -> 'a
(** Unmarshal a string in JSON format as an OCaml value (unsafe but
    fast !).

    Raises [Failure] under the wasm_of_ocaml backend, where the encoding
    of OCaml values is ambiguous (integers and floats both map to
    numbers). *)

(**/**)

val set_use_native_stringify : bool -> unit
(** Only affects js_of_ocaml. Whether to use native Javascript [stringify] to
    turn a value into JSON in {!val:output}. Otherwise, fall back to the slower
    method used by other backends, such as wasm_of_ocaml. *)

val use_native_stringify : unit -> bool
(** Whether js_of_ocaml is using [stringify] in {!val:output}. See
    {!val:set_use_native_stringify}. *)
