8. def ensure[FF >: F](fail: ⇒ FF)(f: (Nothing) ⇒ Boolean): Failure[F]

   

   Turns any success whose underlying value doesn't validate the specified predicate into a failure.

   Turns any success whose underlying value doesn't validate the specified predicate into a failure.

   This is useful when not all successes are interesting. One might receive, for example, a success containing an int, but need to further reduce its domain to positive ints and turn any other into a failure.

16. def forall(f: (Nothing) ⇒ Boolean): Boolean

    

    Returns the result of applying the specified predicate to the underlying value if a success, false otherwise.

17. def foreach(f: (Nothing) ⇒ Unit): Unit

    

    Applies the specified procedure on the underlying value if a success, does nothing otherwise.

    Applies the specified procedure on the underlying value if a success, does nothing otherwise.

    This is useful when one wants to have side-effects that depend on the success' value - print it, for example.

18. def get: Nothing

    

    Returns the underlying value if a success, throws an exception otherwise.

    Returns the underlying value if a success, throws an exception otherwise.

    Other value retrieval methods, such as getOrElse or valueOr, should almost always be preferred.

    Returns the underlying value if a success, the specified default value otherwise.

    Returns the underlying value if a success, the specified default value otherwise.

    This is useful when one needs to provide a default value in case of a failure.

31. def recover[SS](pf: PartialFunction[F, SS]): Result[F, SS]

    

    Turns any failure whose value is defined for specified partial function into a success with the corresponding value.

    Turns any failure whose value is defined for specified partial function into a success with the corresponding value.

    This is useful when some error conditions are actually valid answers - one could imagine, for instance, that failure to parse a boolean could be turned into a successful parsing of false.

    Failure → Result

32. def recoverWith[SS, FF >: F](pf: PartialFunction[F, Result[FF, SS]]): Result[FF, SS]

    

    Turns any failure whose value is defined for specified partial function into the corresponding value.

    Turns any failure whose value is defined for specified partial function into the corresponding value.

    This is useful when some error conditions have fallback solutions - one could imagine, for instance, that failure to parse a file because it does not exist can be retried on a secondary possible location for the file.

35. val toList: Nil.type

    Failure → Result

37. val value: F

    

38. def valueOr[SS](f: (F) ⇒ SS): SS

    

    Returns the underlying value if a success, the result of applying the specified function to the failure value otherwise.

    Returns the underlying value if a success, the result of applying the specified function to the failure value otherwise.

    This is typically useful when one needs to provide a default value that depends on how an operation failed.
