Module Base.Hash_setSource

Sourcetype !'a t
Sourceval sexp_of_t : ('a -> Sexplib0.Sexp.t) -> 'a t -> Sexplib0.Sexp.t

We use [@@deriving sexp_of] but not [@@deriving sexp] because we want people to be explicit about the hash and comparison functions used when creating hashtables. One can use Hash_set.Poly.t, which does have [@@deriving sexp], to use polymorphic comparison and hashing.

Sourceval copy : 'a t -> 'a t

preserves the equality function

Sourceval add : 'a t -> 'a -> unit
Sourceval strict_add : 'a t -> 'a -> unit Or_error.t

strict_add t x returns Ok () if the x was not in t, or an Error if it was.

Sourceval strict_add_exn : 'a t -> 'a -> unit
Sourceval remove : 'a t -> 'a -> unit
Sourceval strict_remove : 'a t -> 'a -> unit Or_error.t

strict_remove t x returns Ok () if the x was in t, or an Error if it was not.

Sourceval inter : 'key t -> 'key t -> 'key t

inter t1 t2 computes the set intersection of t1 and t2. Runs in O(min(length t1, length t2)). Behavior is undefined if t1 and t2 don't have the same equality function.

A hash set that uses polymorphic comparison

M is meant to be used in combination with OCaml applicative functor types:
