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