class (MonadIO m, Applicative m, Functor m) => MonadIO' m

Instances

(MonadIO m, Applicative m, Functor m) => MonadIO' m

ignore :: Monad m => a -> m ()

snoc :: [a] -> a -> [a]

add element to end of list (snoc is reverse of cons, which adds to front of list)

type Secs = Float

bitOr :: Bits a => [a] -> a

bit-or all numbers together

(<.>) :: UString -> UString -> UString

Concat first and second together with period in between. Eg. "hello" <.> "world" = "hello.world"

loop :: (Functor m, Monad m) => m (Maybe a) -> m [a]

Repeatedy execute action, collecting results, until it returns Nothing

true1 :: Label -> Document -> Bool

Is field's value a 1 or True (MongoDB use both Int and Bools for truth values). Error if field not in document or field not a Num or Bool.
