 :  functor (H1 : Hashtbl.HashedType) (H2 : Hashtbl.HashedType) -> sig end

Functor building an implementation of a weak hash table

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

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
