type t = string * int * int

A string, an offset, and the length of the slice.

val make : string -> 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 : t -> int -> Bytes.t -> int -> int -> unit

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

  • raises Invalid_argument

    if indices are not valid.

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

Fold on chars by increasing index.

  • since 0.7

Conversions

val to_gen : t -> char gen

Return the gen of characters contained in the string.

val to_iter : t -> char iter

Return the iter of characters contained in the string.

  • since 2.8
val to_std_seq : t -> char Seq.t

to_std_seq s returns a Seq.t of the bytes in s.

  • since 2.8
val to_seq : t -> char sequence
val to_klist : t -> char klist
val to_list : t -> char list

Return the list of characters contained in the string.

val pp_buf : Buffer.t -> t -> unit

Renamed from pp since 2.0.

val pp : Format.formatter -> t -> unit
