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.
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
