results: Add `isOkOr`, `isErrOr` #176

Closed arnetheduck closed 1 year ago

arnetheduck commented 1 year ago

These two helpers complete valueOr and errorOr to cover void cases where no value should be returned or Result[void, E] / Result[T, void] is being used - they can be used for a convient early-return style in side-effectful proc:s:

v.update().isOkOr:
  echo "update failed: ", error

Great, I've hit that use case several times already :)
