Sourcetype t = char

An alias for the type of characters.

Sourceval equal : t -> t -> bool

The equal function for chars.

  • since 4.03
Sourceval seeded_hash : int -> t -> int

A seeded hash function for characters, with the same output value as Hashtbl.seeded_hash. This function allows this module to be passed as argument to the functor Hashtbl.MakeSeeded.

  • since 5.1
Sourceval hash : t -> int

An unseeded hash function for characters, with the same output value as Hashtbl.hash. This function allows this module to be passed as argument to the functor Hashtbl.Make.

  • since 5.1
Sourceval compare : t -> t -> int

The comparison function for characters, with the same specification as Stdlib.compare. Along with the type t, this function compare allows the module Char to be passed as argument to the functors Set.Make and Map.Make.

Sourceval of_int_exn : int -> t

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

  • since 1.0
Sourceval of_int : int -> t option

Safe version of of_int_exn.

  • since 1.0
