Type Members

  1. final case class LeftProjection[+A, +B](e: Either[A, B]) extends Product with Serializable

    Projects an Either into a Left.

  2. implicit final class MergeableEither[A] extends AnyVal

  3. final case class RightProjection[+A, +B](e: Either[A, B]) extends Product with Serializable

    Projects an Either into a Right.
