(** [sub src ofs len] extract a sub-array of [src] starting at [ofs]

sub-array and the original array share the same storage space. *)
val shift: t -> int -> t
(** [shift src ofs] is equivalent to [sub src ofs (length src - ofs)] *)

(** [blit src ofs_src dst ofs_dst len] copy [len] bytes from [src]
starting at [ofs_src] into [dst] starting at [ofs_dst].] *)

(** [of_string s] create an byte array filled with the same content than [s]. *)

(** [get_int32 buff i] reads 4 bytes at offset i as an int32. *)
