typealias Index = AnyIndexinit(_ other: AnyBidirectionalCollection<Element>) Creates an AnyBidirectionalCollection having the same underlying collection as other.
init?(_ other: AnyCollection<Element>) Creates an AnyBidirectionalCollection having the same underlying collection as other.
init<C>(_ base: C) where Element == C.Element, C : BidirectionalCollection Creates a type-erased collection that wraps the given collection.
init<C>(_ base: C) where Element == C.Element, C : RandomAccessCollection Creates a type-erased collection that wraps the given collection.
init(_ other: AnyRandomAccessCollection<Element>) Creates an AnyBidirectionalCollection having the same underlying collection as other.
var count: Int { get }The number of elements.
var endIndex: AnyBidirectionalCollection<Element>.Index { get }The collection’s “past the end” position—that is, the position one greater than the last valid subscript argument.
var startIndex: AnyBidirectionalCollection<Element>.Index { get }The position of the first element in a non-empty collection.
var underestimatedCount: Int { get }subscript(bounds: Range<AnyBidirectionalCollection<Element>.Index>) -> AnyBidirectionalCollection<Element>.SubSequence { get } subscript(position: AnyBidirectionalCollection<Element>.Index) -> Element { get } Accesses the element indicated by position.
