trait MonadError[F[_], E] extends Serializable with Type[F]

The MonadError type-class describes monads that can do error handling.

To implement MonadError:

The purpose of this type-class is to support the data-types in the Monix library and it is considered a shim for a lawful type-class to be supplied by libraries such as Cats or Scalaz or equivalent.

CREDITS: The type-class encoding has been inspired by the Scato project by Aloïs Cochard and Scalaz 8 and the type has been extracted from Cats.

    Handle any error, potentially recovering from it, by mapping it to an F[A] value.

  6. abstract def onErrorRecover[A](fa: F[A])(pf: PartialFunction[E, A]): F[A]

    Recover from certain errors by mapping them to an A value.

  7. abstract def onErrorRecoverWith[A](fa: F[A])(pf: PartialFunction[E, F[A]]): F[A]

    Recover from certain errors by mapping them to an F[A] value.

  8. abstract def raiseError[A](e: E): F[A]

    Lift an error into the F context.
