Abstract Value Members

  1. abstract def choice[A, B, C](f: F[A, C], g: F[B, C]): F[Either[A, B], C]

    Given two Fs (f and g) with a common target type, create a new F with the same target type, but with a source type of either f's source type OR g's source type.

    Given two Fs (f and g) with a common target type, create a new F with the same target type, but with a source type of either f's source type OR g's source type.

    Example:

    scala> import cats.implicits._
    scala> val b: Boolean => String = _ + " is a boolean"
    scala> val i: Int => String =  _ + " is an integer"
    scala> val f: (Either[Boolean, Int]) => String = b ||| i
    
    scala> f(Right(3))
    res0: String = 3 is an integer
    
    scala> f(Left(false))
    res0: String = false is a boolean
