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 JoinedByClosureSequence<Base, Separator> where Base : Sequence, Separator : Sequence, Base.Element : Sequence, Separator.Element == Base.Element.ElementA sequence that presents the elements of a base sequence of sequences concatenated using a given separator that depends on the sequences 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.
@frozen struct CollectionOfOne<Element>A collection containing a single element.
protocol Sequence<Element>A type that provides sequential, iterated access to its elements.
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<Separator>(by separator: @escaping (Element, Element) -> Separator) -> JoinedByClosureCollection<Elements, Separator> where Separator : Collection, Separator.Element == Self.Element.Element Returns the concatenation of the elements in this collection of collections, inserting the separator produced by the closure between each sequence.
func joined<Separator>(by separator: @escaping (Element, Element) -> Separator) -> JoinedByClosureSequence<Elements, Separator> 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.
