Module `CCUtf8_string`

Unicode String, in UTF8

type uchar = Stdlib.Uchar.t
type 'a gen = unit -> 'a option
type 'a sequence = ('a -> unit) -> unit
type t = private string: A UTF8 string

val equal : t -> t -> bool
val hash : t -> int
val compare : t -> t -> int
val pp : Stdlib.Format.formatter -> t -> unit
val to_string : t -> string: Identity.

exception Malformed of string * int: Malformed string at given offset

val to_gen : ?⁠idx:int -> t -> uchar gen

Generator of unicode codepoints.

parameter idx: offset where to start the decoding.

val to_seq : ?⁠idx:int -> t -> uchar sequence

Iter of unicode codepoints.

parameter idx: offset where to start the decoding.

val to_list : ?⁠idx:int -> t -> uchar list

List of unicode codepoints.

parameter idx: offset where to start the decoding.

val fold : ?⁠idx:int -> ('a -> uchar -> 'a) -> 'a -> t -> 'a
val iter : ?⁠idx:int -> (uchar -> unit) -> t -> unit
val n_chars : t -> int: Number of characters.

val n_bytes : t -> int: Number of bytes.

val map : (uchar -> uchar) -> t -> t

val filter_map : (uchar -> uchar option) -> t -> t

val flat_map : (uchar -> t) -> t -> t

val append : t -> t -> t

val concat : t -> t list -> t

val of_seq : uchar sequence -> t

val of_gen : uchar gen -> t

val of_list : uchar list -> t

val of_string_exn : string -> t

Validate string by checking it is valid UTF8.

raises Invalid_argument: if the string is not valid UTF8.

val of_string : string -> t option: Safe version of of_string_exn.

val is_valid : string -> bool: Valid UTF8?

val unsafe_of_string : string -> t: Conversion from a string without validating. Upon iteration, if an invalid substring is met, Malformed will be raised.
