NAME
       Ephemeron.S - The output signature of the functor Ephemeron.K1.Make and
       Ephemeron.K2.Make.

Module type
       Module type   Ephemeron.S

Documentation
       Module type S
        = sig end

       The   output   signature   of   the   functor   Ephemeron.K1.Make   and
       Ephemeron.K2.Make .  These hash tables are weak in the keys. If all the
       keys of a binding are alive the binding is kept, but if one of the keys
       of the binding is dead then the binding is removed.

       Propose the same interface as usual hash table. However since the bind-
       ings are weak, even if mem h k is true, a subsequent find h k may raise
       Not_found because the garbage collector can run between the two.

       Moreover,  the table shouldn't be modified during a call to iter .  Use
       filter_map_inplace in this case.

       include Hashtbl.S

       val clean : 'a t -> unit

       remove all dead bindings. Done automatically during automatic resizing.

       val stats_alive : 'a t -> Hashtbl.statistics

       same as Hashtbl.SeededS.stats but only count the alive bindings
