Implicit conversion from NonEmptyList
to List
.
Implicit conversion from NonEmptyList
to List
.
One use case for this implicit conversion is to enable GenSeq[NonEmptyList]
s to be flattened.
Here's an example:
scala> Vector(NonEmptyList(1, 2, 3), NonEmptyList(3, 4), NonEmptyList(5, 6, 7, 8)).flatten res0: scala.collection.immutable.Vector[Int] = Vector(1, 2, 3, 3, 4, 5, 6, 7, 8)
the NonEmptyList
to convert to a List
a List
containing the elements, in order, of this NonEmptyList
