Value Members

  1. def from[G, B](option: Option[G], orElse: => B): Or[G, B]

    Constructs a new Or from the given Option.

    Constructs a new Or from the given Option.

    option

    the Option to convert to an Or

    orElse

    the Bad value to use if the Option passed as option is None.

    returns

    a new Or whose Good type is the Option's type and whose Bad type is the type of the passed orElse parameter.

  2. def from[B, G](either: Either[B, G]): Or[G, B]

    Constructs a new Or from the given Either.

    Constructs a new Or from the given Either.

    Note that values effectively “switch sides” when converting an Either to an Or. If the type of the Either which you pass to Or.from is Either[ErrorMessage, Int] for example, the result will be an Or[Int, ErrorMessage]. The reason is that the convention for Either is that Left is used for “bad” values and Right is used for “good” ones. If you with to keep the types on the same side, invoke swap on the Either before passing it to from.

    either

    the Either to convert to an Or

    returns

    a new Or whose Good type is the Either's Right type and whose Bad type is Either's Left type.

  3. def from[G](theTry: Try[G]): Or[G, Throwable]

    Constructs a new Or from the given Try.

    Constructs a new Or from the given Try.

    theTry

    the Try to convert to an Or

    returns

    a new Or whose Good type is the Try's Success type and whose Bad type is Throwable.
