5. def catchNonFatal[A](f: ⇒ A): Either[Throwable, A]

   

6. def catchOnly[T >: Null <: Throwable]: CatchOnlyPartiallyApplied[T]

   

   Evaluates the specified block, catching exceptions of the specified type and returning them on the left side of the resulting Either.

   Evaluates the specified block, catching exceptions of the specified type and returning them on the left side of the resulting Either. Uncaught exceptions are propagated.

   For example:

   scala> import cats.implicits._ // get syntax for Either
   scala> Either.catchOnly[NumberFormatException] { "foo".toInt }
   res0: Either[NumberFormatException, Int] = Left(java.lang.NumberFormatException: For input string: "foo")

7. def fromOption[A, B](o: Option[B], ifNone: ⇒ A): Either[A, B]

   

   Converts an Option[B] to an Either[A, B], where the provided ifNone values is returned on the left of the Either when the specified Option is None.

8. def fromTry[A](t: Try[A]): Either[Throwable, A]

   

   Converts a Try[A] to a Either[Throwable, A].
