Module `CCStringLabels.Sub`

type t = string * int * int: A string, an offset, and the length of the slice.

val make : string -> pos:int -> len:int -> t
val full : string -> t: Full string.

val copy : t -> string: Make a copy of the substring.

val underlying : t -> string
val sub : t -> int -> int -> t: Sub-slice.

val get : t -> int -> char

get s i gets the i-th element, or fails.

raises Invalid_argument: if the index is not within 0 ... length - 1.

since: 1.2

include S with type t := t

val length : t -> int: Return the length (number of characters) of the given string.

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

Like String.blit. Compatible with the -safe-string option.

raises Invalid_argument: if indices are not valid.

val fold : f:('a -> char -> 'a) -> init:'a -> t -> 'a

Fold on chars by increasing index.
