protocol LazySequenceProtocol : SequenceA sequence on which normally-eager sequence operations are implemented lazily.
associatedtype Element where Self.Element == Self.Iterator.ElementA type representing the sequence’s elements.
struct JoinedByClosureCollection<Base, Separator> where Base : Collection, Separator : Collection, Base.Element : Collection, Separator.Element == Base.Element.ElementA collection that presents the elements of a base collection of collections concatenated using a given separator that depends on the collections right before and after it.
associatedtype Elements : Sequence = Self where Self.Element == Self.Elements.ElementA Sequence that can contain the same elements as this one, possibly with a simpler type.
protocol Collection<Element> : SequenceA sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.
func joined<Separator>(by separator: Separator) -> JoinedBySequence<Self, Separator> where Separator : Collection, Separator.Element == Self.Element.Element Returns the concatenation of the elements in this sequence of sequences, inserting the given separator between each sequence.
func joined<Separator>(by separator: (Element, Element) throws -> Separator) rethrows -> [Element.Element] where Separator : Sequence, Separator.Element == Self.Element.Element Returns the concatenation of the elements in this sequence of sequences, inserting the separator produced by the closure between each sequence.
func joined<Separator>(by separator: Separator) -> JoinedByCollection<Self, Separator> where Separator : Collection, Separator.Element == Self.Element.Element Returns the concatenation of the elements in this collection of collections, inserting the given separator between each collection.
func joined(by separator: @escaping (Element, Element) -> Element.Element) -> JoinedByClosureSequence<Elements, CollectionOfOne<Element.Element>> Returns the concatenation of the elements in this sequence of sequences, inserting the separator produced by the closure between each sequence.
func joined(by separator: @escaping (Element, Element) -> Element.Element) -> JoinedByClosureCollection<Elements, CollectionOfOne<Element.Element>> Returns the concatenation of the elements in this collection of collections, inserting the separator produced by the closure between each sequence.
