Bytes and Strings

In 4.02.0, s.[i] <- c becomes deprecated and this is very frustrating for CamlImages.

We introduce (<<) and replace them by s << i & c.

val (&) : ('a -> 'b) -> 'a -> 'b
val (<<) : bytes -> int -> char -> unit

equivalent with Bytes.set

val (<<!) : bytes -> int -> char -> unit

equivalent with Bytes.unsafe_set

val range_check : bytes -> int -> int -> unit

range_check bs from to_ raises Invalid_argument "index out of bounds" when from and to_ are invalid range for bs.

val (>@!) : 'a array -> int -> 'a

equivalent with Array.unsafe.get

val (@%) : bytes -> int -> int

s @% p = Char.code @@ Bytes.get s p
