Module Set.Make_plain

Make builds a set from an element type that has a compare function but doesn't have a comparator. This generates a new comparator.

Make_binable is similar, except the element and set types support bin_io.

Parameters

module Elt : Elt_plain

Signature

module Elt : sig ... end
val compare : t -> t -> Base.Int.t
val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t
include Set_intf.Creators_and_accessors0 with type ('a, 'b) set := ('a, 'b) Base.Set.t with type t := t with type tree := Tree.t with type elt := Elt.t with type named := named with type comparator_witness := Elt.comparator_witness

val length : t -> int
val is_empty : t -> bool
val iter : t -> f:(Elt.t -> unit) -> unit

iter must allow exceptions raised in f to escape, terminating the iteration cleanly. The same holds for all functions below taking an f.

val fold : t -> init:'accum -> f:('accum -> Elt.t -> 'accum) -> 'accum

fold t ~init ~f returns f (... f (f (f init e1) e2) e3 ...) en, where e1..en are the elements of t.

val fold_result : t -> init:'accum -> f:('accum -> Elt.t -> ('accum, 'e) Base.Result.t) -> ('accum, 'e) Base.Result.t

fold_result t ~init ~f is a short-circuiting version of fold that runs in the Result monad. If f returns an Error _, that value is returned without any additional invocations of f.

val exists : t -> f:(Elt.t -> bool) -> bool

Returns true if and only if there exists an element for which the provided function evaluates to true. This is a short-circuiting operation.

val for_all : t -> f:(Elt.t -> bool) -> bool

Returns true if and only if the provided function evaluates to true for all elements. This is a short-circuiting operation.

val count : t -> f:(Elt.t -> bool) -> int

Returns the number of elements for which the provided function evaluates to true.

val sum : (module Base__Container_intf.Summable with type t = 'sum) -> t -> f:(Elt.t -> 'sum) -> 'sum

Returns the sum of f i for all i in the container.

val find : t -> f:(Elt.t -> bool) -> Elt.t option

Returns as an option the first element for which f evaluates to true.

val find_map : t -> f:(Elt.t -> 'a option) -> 'a option

Returns the first evaluation of f that returns Some, and returns None if there is no such element.
