Functor Ephemeron.K2.Make

module Make:
  (H1: Hashtbl.HashedType, H2: Hashtbl.HashedType) =>
   Ephemeron.S with type key = (H1.t, H2.t);

Parameters:

H1 : Hashtbl.HashedType H2 : Hashtbl.HashedType

---

Propose the same interface as usual hash table. However since the bindings 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;

let clean: t('a) => unit;

let stats_alive: t('a) => Hashtbl.statistics;
