Functor building an implementation of a weak hash table

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.

Parameters

module H1 : Hashtbl.HashedType

module H2 : Hashtbl.HashedType

Signature

include Hashtbl.S with type key = H1.t * H2.t

type key = H1.t * H2.t
