Module Set.Poly

A polymorphic Set.

val length : 'a t -> int
val is_empty : 'a t -> bool
val iter : 'a t -> f:( 'a -> unit ) -> unit
val fold : 'a t -> init:'accum -> f:( 'accum -> 'a -> '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 : 'a t -> init:'accum -> f:( 'accum -> 'a -> ( 'accum, 'e ) Result.t ) -> ( 'accum, 'e ) 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 : 'a t -> f:( 'a -> 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 : 'a t -> f:( 'a -> 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 : 'a t -> f:( 'a -> 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) -> 'a t -> f:( 'a -> 'sum ) -> 'sum

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

val find : 'a t -> f:( 'a -> bool ) -> 'a option

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

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

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