whileMFinalIO :: Sem r Bool -> Sem r () Source #
Like whileM, but stateful effects are not preserved to mitigate memory leaks
This means Polysemy.Error won't work to break the loop, etc. Instead, Error/Alternative will just result in the loop quitting.
untilJustFinalIO :: Member (Final IO) r => Sem r (Maybe a) -> Sem r a Source #
Like untilJust, but stateful effects are not preserved to mitigate memory leaks
This means Polysemy.Error won't work to break the loop, etc. Instead, Error/Alternative will just result in another loop.

An alternative Maybe type that allows us to distinguish between parsed
json fields that were null, and fields that didn't exist.
