Bigstring helpers for shexp libraries

type t =
  (char, Stdlib.Bigarray.int8_unsigned_elt, Stdlib.Bigarray.c_layout)
    Stdlib.Bigarray.Array1.t

val create : int -> t

val length : t -> int

val blit : src:t -> src_pos:int -> dst:t -> dst_pos:int -> len:int -> unit

val blit_string_t : 
  src:string ->
  src_pos:int ->
  dst:t ->
  dst_pos:int ->
  len:int ->
  unit

val blit_t_bytes : 
  src:t ->
  src_pos:int ->
  dst:Stdlib.Bytes.t ->
  dst_pos:int ->
  len:int ->
  unit

val sub_string : t -> pos:int -> len:int -> string

val index : t -> pos:int -> len:int -> char:char -> int option

val rindex : t -> pos:int -> len:int -> char:char -> int option

val pos_len_ok : pos:int -> len:int -> length:int -> bool

Efficiently checks that the range denoted by (pos, len) is in the range 0..length. length is assumed to be >= 0.

val check_pos_len_exn : pos:int -> len:int -> length:int -> unit

Raises if (pos, len) denotes a range outside of 0..length.

val with_temporary : size:int -> f:(t -> 'a) -> 'a

Allocate a bigstring and pass it to f. The memory allocated for the bigstring is released as soon as f returns. As such, the bigstring shouldn't be used after f returns.

This is more efficient than waiting on the garbage collector to release the external memory.

type ('a, 'b) fold_temporary_result =

| Resize of {
1. new_size : int;
2. state : 'a;
}
| Continue of {
1. state : 'a;
}
(*
Same as Resize with the same size
*)
| Return of 'b

val fold_temporary : 
  size:int ->
  init:'a ->
  f:(t -> 'a -> ('a, 'b) fold_temporary_result) ->
  'b

Same as with_temporary, but allow to resize the bigstring if needed.

If f returns Resize { new_size; state }, the bigstring will be resized to the given new size and f will be called with the new bigstring and state. The contents of the bigstring up to the min of the old and new sizes is preserved.
