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 Ephemeron

let 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).

let length: t => int;

return the number of keys
