The collection’s “past the end” position—that is, the position one greater than the last valid subscript argument.
var endIndex: LazySequence<Base>.Index { get }where Base:CollectionendIndex is always reachable from startIndex by zero or more applications of index(after:).
import Swift@frozen struct LazySequence<Base> where Base : SequenceA sequence containing the same elements as a Base sequence, but on which some operations such as map and filter are implemented lazily.
protocol Collection<Element> : SequenceA sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.
var count: Int { get }Returns the number of elements.
var indices: LazySequence<Base>.Indices { get }var isEmpty: Bool { get }A Boolean value indicating whether the collection is empty.
var startIndex: LazySequence<Base>.Index { get }The position of the first element in a non-empty collection.
subscript(position: LazySequence<Base>.Index) -> LazySequence<Base>.Element { get } Accesses the element at position.
