# Module Obj.Ephemeron

    module Ephemeron: sig .. end

Ephemeron with arbitrary arity and untyped

    type obj_t = Obj.t

alias for `Obj.t`

    type t

an ephemeron cf `Obj.Ephemeron`

    val create : int -> t

`create n` returns an ephemeron with `n` keys. All the keys and the data are initially empty. The argument `n` must be between zero and `Obj.Ephemeron.max_ephe_length` (limits included).

    val length : t -> int

return the number of keys
