Associated Types
Generator : GeneratorType = IndexingGenerator<Self>

A type that provides the sequence's iteration interface and encapsulates its iteration state.

By default, a CollectionType satisfies SequenceType by supplying an IndexingGenerator as its associated Generator type.

SubSequence : Indexable, SequenceType = Slice<Self>

A SequenceType that can represent a contiguous subrange of self's elements.

Note: this associated type appears as a requirement in SequenceType, but is restated here with stricter constraints: in a CollectionType, the SubSequence should also be a CollectionType.

Index : ForwardIndexType

A type that represents a valid position in the collection.

Valid indices consist of the position of every element and a "past the end" position that's not valid for use as a subscript.
