Module Weak_hashtbl_asyncSource

Like Weak_hashtbl, but automatically collects keys with unused data, rather than requiring user code to call remove_keys_with_unused_data.

include module type of Weak_hashtbl
Sourcetype ('a, 'b) t
Sourceval sexp_of_t : ('a -> Sexplib0.Sexp.t) -> ('b -> Sexplib0.Sexp.t) -> ('a, 'b) t -> Sexplib0.Sexp.t
Sourceval create : ?growth_allowed:bool -> ?size:int -> (module Weak_hashtbl__.Import.Hashtbl.Key_plain with type t = 'a) -> ('a, 'b) t

growth_allowed and size are both optionally passed on to the underlying call to Hashtbl.create.

Sourcemodule Using_hashable : sig ... end
Sourceval mem : ('a, _) t -> 'a -> bool
Sourceval find : ('a, 'b) t -> 'a -> 'b Core.Heap_block.t option
Sourceval find_or_add : ('a, 'b) t -> 'a -> default:(unit -> 'b Core.Heap_block.t) -> 'b Core.Heap_block.t
Sourceval remove : ('a, 'b) t -> 'a -> unit
Sourceval add_exn : ('a, 'b) t -> key:'a -> data:'b Core.Heap_block.t -> unit
Sourceval replace : ('a, 'b) t -> key:'a -> data:'b Core.Heap_block.t -> unit
Sourceval key_is_using_space : ('a, _) t -> 'a -> bool

key_is_using_space t key returns true if key is using some space in t. mem t key implies key_is_using_space t key, but it is also possible that that key_is_using_space t key && not (mem t key).
