import Swift@frozen struct FlattenSequence<Base> where Base : Sequence, Base.Element : SequenceA sequence consisting of all the elements contained in each segment contained in some Base sequence.
@frozen struct IndexA position in a FlattenCollection
protocol Collection<Element> : SequenceA sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.
var endIndex: FlattenSequence<Base>.Index { get }The collection’s “past the end” position.
subscript(position: FlattenSequence<Base>.Index) -> Base.Element.Element { get } Accesses the element at position.
