Here's an example:
scala> 1 :: End res0: org.scalactic.NonEmptyList[Int] = NonEmptyList(1)
Returns "End"
.
Returns "End"
.
Object that can be used as an endpoint for
NonEmptyList
construction expressions that use the cons (::
) operator.Here's an example:
Note that unlike
Nil
, which is an instance ofList[Nothing]
,End
is not an instance ofNonEmptyList[Nothing]
, because there is no emptyNonEmptyList
