Hashtbl.SeededS(3)

✨ NAME ✨

Hiii bestie 💖 welcome to Hashtbl.SeededS(3) from the OCaml library manual. This page is lowkey the output signature of the functor Hashtbl.MakeSeeded — it's giving "contract, but make it cute" ✨.

Module type Hashtbl.SeededS

🌸 Documentation 🌸

Okay so, the module type is literally:

Module type SeededS = sig end

And fr fr, this is the output signature of the functor Hashtbl.MakeSeeded. Since 4.00 — an icon, no cap 👑.

Here's the whole signature lineup, in order, nothing skipped:

• type key
• type !'a t
• val create : ?random:bool -> int -> 'a t
• val clear : 'a t -> unit
• val reset : 'a t -> unit
• val copy : 'a t -> 'a t
• val add : 'a t -> key -> 'a -> unit
• val remove : 'a t -> key -> unit
• val find_and_remove : 'a t -> key -> 'a option — Since 5.5
• val find : 'a t -> key -> 'a
• val find_opt : 'a t -> key -> 'a option — Since 4.05
• val find_all : 'a t -> key -> 'a list
• val replace : 'a t -> key -> 'a -> unit
• val find_and_replace : 'a t -> key -> 'a -> 'a option — Since 5.5
• val mem : 'a t -> key -> bool
• val iter : (key -> 'a -> unit) -> 'a t -> unit
• val filter_map_inplace : (key -> 'a -> 'a option) -> 'a t -> unit — Since 4.03
• val fold : (key -> 'a -> 'acc -> 'acc) -> 'a t -> 'acc -> 'acc
• val length : 'a t -> int
• val stats : 'a t -> Hashtbl.statistics
• val to_seq : 'a t -> (key * 'a) Seq.t — Since 4.07
• val to_seq_keys : 'a t -> key Seq.t — Since 4.07
• val to_seq_values : 'a t -> 'a Seq.t — Since 4.07
• val add_seq : 'a t -> (key * 'a) Seq.t -> unit — Since 4.07
• val replace_seq : 'a t -> (key * 'a) Seq.t -> unit — Since 4.07

That's the whole thing, bestie — every type and val is up there, looking cute and fully accounted for 🫶. xoxo, OCamldoc, 2026-06-22 🌈💅
