Value members

Concrete methods

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.

Value parameters:
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.

Source:
Or.scala
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.

Value parameters:
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.

Or.scala
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.

Value parameters:
option

orElse

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