(* String operations, without sanity checks *)

(* This module implements the same functions as the [string] module,
   but does not perform bound checks on the arguments of the functions.
   The functions are therefore faster than those in the [string] module,
   but calling these functions with incorrect parameters (that is,
   parameters that would cause the [Invalid_argument] exception to be raised
   by the corresponding functions in the [string] module) can crash the
   program. *)
