  5. def andThen[EE >: E, B](f: (A) ⇒ Validated[EE, B]): Validated[EE, B]

    Apply a function (that returns a Validated) in the valid case.

    Apply a function (that returns a Validated) in the valid case. Otherwise return the original Validated.

    This allows "chained" validation: the output of one validation can be fed into another validation function.

    This function is similar to flatMap on Either. It's not called flatMap, because by Cats convention, flatMap is a monadic bind that is consistent with ap. This method is not consistent with ap (or other Apply-based methods), because it has "fail-fast" behavior as opposed to accumulating validation failures.

  6. def ap[EE >: E, B](f: Validated[EE, (A) ⇒ B])(implicit EE: Semigroup[EE]): Validated[EE, B]

    From Apply: if both the function and this value are Valid, apply the function

  10. def combine[EE >: E, AA >: A](that: Validated[EE, AA])(implicit EE: Semigroup[EE], AA: Semigroup[AA]): Validated[EE, AA]

    Combine this Validated with another Validated, using the Semigroup instances of the underlying E and A instances.

    Combine this Validated with another Validated, using the Semigroup instances of the underlying E and A instances. The resultant Validated will be Valid, if, and only if, both this Validated instance and the supplied Validated instance are also Valid.

  12. def ensure[EE >: E](onFailure: ⇒ EE)(f: (A) ⇒ Boolean): Validated[EE, A]

    Ensure that a successful result passes the given predicate, falling back to an Invalid of onFailure if the predicate returns false.

    Ensure that a successful result passes the given predicate, falling back to an Invalid of onFailure if the predicate returns false.

    For example:

    scala> Validated.valid("").ensure(new IllegalArgumentException("Must not be empty"))(_.nonEmpty)
    res0: Validated[IllegalArgumentException, String] = Invalid(java.lang.IllegalArgumentException: Must not be empty)
  13. def ensureOr[EE >: E](onFailure: (A) ⇒ EE)(f: (A) ⇒ Boolean): Validated[EE, A]

    Ensure that a successful result passes the given predicate, falling back to the an Invalid of the result of onFailure if the predicate returns false.

    Ensure that a successful result passes the given predicate, falling back to the an Invalid of the result of onFailure if the predicate returns false.

    For example:

    scala> Validated.valid("ab").ensureOr(s => new IllegalArgumentException("Must be longer than 3, provided '" + s + "'"))(_.length > 3)
    res0: Validated[IllegalArgumentException, String] = Invalid(java.lang.IllegalArgumentException: Must be longer than 3, provided 'ab')

  18. def findValid[EE >: E, AA >: A](that: ⇒ Validated[EE, AA])(implicit EE: Semigroup[EE]): Validated[EE, AA]

    If this is valid return this, otherwise if that is valid return that, otherwise combine the failures.

    If this is valid return this, otherwise if that is valid return that, otherwise combine the failures. This is similar to orElse except that here failures are accumulated.

  19. def fold[B](fe: (E) ⇒ B, fa: (A) ⇒ B): B

  21. def foldRight[B](lb: Eval[B])(f: (A, Eval[B]) ⇒ Eval[B]): Eval[B]

    Lazily-apply the given function to the value with the given B when valid, otherwise return the given B.

  22. def forall(f: (A) ⇒ Boolean): Boolean
