Constant Summary collapse

Unit = Unit is a singleton, and is used when there is no other meaningful value that could be returned. It allows the Result implementation to distinguish between a null value (i.e. nil) and the lack of a value, to provide adequate behavior in each case. The Result API should not expose Unit directly to its consumers. See Also: https://en.wikipedia.org/wiki/Unit_type
