ASCII characters

Sourcemodule Ascii = Char.Ascii

ASCII character set support.

Sourceval lowercase_ascii : char -> char

Use the equivalent Ascii.lowercase instead.

  • since 4.03
Sourceval uppercase_ascii : char -> char

Use the equivalent Ascii.uppercase instead.

Hashing

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
