Parameters

module E : ELEMENT

Signature

type t
type elt = E.t
val create : int -> t

create n makes a new set with the given capacity n.

val singleton : elt -> t

singleton x is the singleton {x}.

val clear : t -> unit

clear s removes all elements from s.

val copy : t -> t

Fresh copy.

val copy_into : into:t -> t -> unit

copy_into ~into s copies all elements of s into into.

val insert : t -> elt -> unit

insert s x adds x into s.

val remove : t -> elt -> unit

Remove the element, if it were in there.

val cardinal : t -> int

cardinal s returns the number of elements in s.

val mem : t -> elt -> bool

mem s x returns true iff x is in s.

val find_exn : t -> elt -> elt

find_exn s x returns y if x and y are equal, and mem s y.

val find : t -> elt -> elt option

Safe version of find_exn.

val inter : t -> t -> t

inter a b returns a ∩ b.

val inter_mut : into:t -> t -> unit

inter_mut ~into a changes into into a ∩ into.

val union : t -> t -> t

union a b returns a ∪ b.

val union_mut : into:t -> t -> unit

union_mut ~into a changes into into a ∪ into.

val diff : t -> t -> t

diff a b returns a - b.

val subset : t -> t -> bool

subset a b returns true if all elements of a are in b.

val equal : t -> t -> bool

equal a b is extensional equality (a and b have the same elements).

val for_all : (elt -> bool) -> t -> bool
val exists : (elt -> bool) -> t -> bool
val iter : (elt -> unit) -> t -> unit

Iterate on values.

val fold : ('a -> elt -> 'a) -> 'a -> t -> 'a

Fold on values.

val elements : t -> elt list

List of elements.

val of_list : elt list -> t
val to_seq : t -> elt sequence
val of_seq : elt sequence -> t
val add_seq : t -> elt sequence -> unit
val pp : ?sep:string -> elt printer -> t printer

pp pp_elt returns a set printer, given a printer for individual elements.
