Index

import Swift

@frozen struct DefaultIndices<Elements> where Elements : Collection

A collection of indices for an arbitrary collection

associatedtype Index : Comparable where Self.Index == Self.Indices.Element, Self.Indices.Element == Self.Indices.Index, Self.Indices.Index == Self.SubSequence.Index

A type that represents a position in the collection.

protocol Collection<Element> : Sequence

A sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.
