val code : char -> int
val chr : int -> char
val escaped : char -> string
val lowercase_ascii : char -> char
val uppercase_ascii : char -> char
type t = char
val compare : t -> t -> int
val equal : t -> t -> bool
val seeded_hash : int -> t -> int
val hash : t -> int
val unsafe_chr : int -> char
val of_int_exn : int -> t

Alias to Char.chr. Return the character with the given ASCII code.

  • raises Invalid_argument

    if the int is not within 0 … 255.

  • since 1.0
val of_int : int -> t option

Safe version of of_int_exn.

  • since 1.0
val to_int : t -> int

Alias to Char.code. Return the ASCII code of the argument.

  • since 1.0
val to_string : t -> string

to_string c returns a string containing c

  • since 2.7
val pp_buf : Buffer.t -> t -> unit

Renamed from pp since 2.0.

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

Renamed from print since 2.0.

val is_uppercase_ascii : t -> bool

is_uppercase_ascii c is true exactly when c is an uppercase ASCII character, i.e. '\064' < c < '\091'.

  • since 3.16
val is_lowercase_ascii : t -> bool

is_lowercase_ascii c is true exactly when c is a lowercase ASCII character, i.e. '\096' < c < '\123'.

  • since 3.16
val is_letter_ascii : t -> bool

is_letter_ascii c is true exactly when c is an ASCII letter, i.e. is_uppercase_ascii c || is_lowercase_ascii c.

  • since 3.16
val is_digit_ascii : t -> bool

is_digit_ascii c is true exactly when c is an ASCII digit, i.e. '\047' < c < '\058'.

  • since 3.16
val is_whitespace_ascii : t -> bool

is_whitespace_ascii c is true exactly when c is an ASCII whitespace character as defined by Unicode, i.e. either c = ' ' or '\008' < c < '\014'.

  • since 3.16
