Associated Type

SubSequence

A sequence that represents a contiguous subrange of the collection’s elements.

Required.

Declaration

associatedtype SubSequence : _IndexableBase, Sequence = Slice<Self> where Self.Element == Self.SubSequence.Element, Self.SubSequence == Self.SubSequence.SubSequence

Discussion

This associated type appears as a requirement in the Sequence protocol, but it is restated here with stricter constraints. In a collection, the subsequence should also conform to Collection.
