subscript(_:)
subscript(bounds: Range<Int>) -> CollectionOfOne<Element>.SubSequence { get set } subscript(bounds: Range<Int>) -> CollectionOfOne<Element>.SubSequence { get set } import Swift@frozen struct CollectionOfOne<Element>A collection containing a single element.
@frozen struct Range<Bound> where Bound : ComparableA half-open interval from a lower bound up to, but not including, an upper bound.
@frozen struct IntA signed integer value type.
typealias SubSequence = Slice<CollectionOfOne<Element>>init(_ element: Element) Creates an instance containing just the given element.
var count: Int { get }The number of elements in the collection, which is always one.
var customMirror: Mirror { get }var debugDescription: String { get }A textual representation of the collection, suitable for debugging.
var endIndex: CollectionOfOne<Element>.Index { get }The “past the end” position—that is, the position one greater than the last valid subscript argument.
var startIndex: CollectionOfOne<Element>.Index { get }The position of the first element.
subscript(position: Int) -> Element { get set } Accesses the element at the specified position.
func index(after i: CollectionOfOne<Element>.Index) -> CollectionOfOne<Element>.Index Returns the position immediately after the given index.
func index(before i: CollectionOfOne<Element>.Index) -> CollectionOfOne<Element>.Index Returns the position immediately before the given index.
func makeIterator() -> CollectionOfOne<Element>.Iterator Returns an iterator over the elements of this collection.
@frozen struct IteratorAn iterator that produces one or zero instances of an element.
