FlattenSequence

A sequence consisting of all the elements contained in each segment contained in some Base sequence.

@frozen struct FlattenSequence<Base> where Base : Sequence, Base.Element : Sequence

Overview

The elements of this view are a concatenation of the elements of each sequence in the base.

The joined method is always lazy, but does not implicitly confer laziness on algorithms applied to its result. In other words, for ordinary sequences s:

  • s.joined() does not create new storage

  • s.joined().map(f) maps eagerly and returns a new array

  • s.lazy.joined().map(f) maps lazily and returns a LazyMapSequence
