Functor Ephemeron.Kn.Make

module Make: functor (H : Hashtbl.HashedType) -> Ephemeron.S  with type key = H.t array

Functor building an implementation of a weak hash table

Parameters:

H : 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
