def apply[G]: GoodType[G]

Captures a Good type to enable a Bad to be constructed with a specific Good type.

Captures a Good type to enable a Bad to be constructed with a specific Good type.

Because Or has two types, but the Bad factory method only takes a value of the “bad” type, the Scala compiler will infer Nothing for the Good type:

scala> Bad("oops")
res1: org.scalactic.Bad[Nothing,String] = Bad(oops)

Often Nothing will work fine, as it will be widened as soon as the compiler encounters a more specific Good type. Sometimes, however, you may need to specify it. In such situations you can use this factory method, like this:

scala> Good[Int].orBad("oops")
res3: org.scalactic.Bad[Int,String] = Bad(oops)
