Module Map.OfSource

This functor lets you describe the type of Maps a little more concisely.

  let string_to_int : int Map.Of(String).t =
    Map.from_list (module String) [("Apple", 2); ("Pear", 0)]

Is the same as

  let string_to_int : (string, int, String.identity) Map.t =
    Map.from_list (module String) [("Apple", 2); ("Pear", 0)]

Parameters

module M : sig ... end
