protocol CxxRandomAccessCollection<Element> : CxxSequence, RandomAccessCollection where Self.RawIterator : UnsafeCxxRandomAccessIteratorprotocol CxxRandomAccessCollection<Element> : CxxSequence, RandomAccessCollection where Self.RawIterator : UnsafeCxxRandomAccessIteratorimport Cxxassociatedtype Elementprotocol CxxSequence<Element> : CxxConvertibleToCollection, SequenceUse this protocol to conform custom C++ sequence types to Swift’s Sequence protocol like this:
protocol RandomAccessCollection<Element> : BidirectionalCollection where Self.Indices : RandomAccessCollection, Self.SubSequence : RandomAccessCollectionA collection that supports efficient random-access index traversal.
associatedtype RawIterator : UnsafeCxxInputIteratorprotocol UnsafeCxxRandomAccessIterator : UnsafeCxxInputIteratorBridged C++ iterator that allows computing the distance between two of its instances, and advancing an instance by a given number of elements.
protocol BidirectionalCollection<Element> : Collection where Self.Indices : BidirectionalCollection, Self.SubSequence : BidirectionalCollectionA collection that supports backward as well as forward traversal.
protocol Collection<Element> : SequenceA sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.
protocol CxxConvertibleToCollection<Element>A C++ type that can be converted to a Swift collection.
protocol Sequence<Element>A type that provides sequential, iterated access to its elements.

This overload should only be used if the C++ type does not define operator[].
