Instance Property

lazy

A sequence containing the same elements as this sequence, but on which some operations, such as map and filter, are implemented lazily.

Declaration

var lazy: LazySequence<Range<Bound>> { get }
Available when Bound conforms to Strideable and Bound.Stride conforms to SignedInteger.
