Methods

gfoldl :: (forall d b. Data d => c (d -> b) -> d -> c b) -> (forall g. g -> c g) -> ExceptState state e -> c (ExceptState state e)

gunfold :: (forall b r. Data b => c (b -> r) -> c r) -> (forall r. r -> c r) -> Constr -> c (ExceptState state e)

toConstr :: ExceptState state e -> Constr

dataTypeOf :: ExceptState state e -> DataType

dataCast1 :: Typeable t => (forall d. Data d => c (t d)) -> Maybe (c (ExceptState state e))

dataCast2 :: Typeable t => (forall d e0. (Data d, Data e0) => c (t d e0)) -> Maybe (c (ExceptState state e))

gmapT :: (forall b. Data b => b -> b) -> ExceptState state e -> ExceptState state e

gmapQl :: (r -> r' -> r) -> r -> (forall d. Data d => d -> r') -> ExceptState state e -> r

gmapQr :: forall r r'. (r' -> r -> r) -> r -> (forall d. Data d => d -> r') -> ExceptState state e -> r

gmapQ :: (forall d. Data d => d -> u) -> ExceptState state e -> [u]

gmapQi :: Int -> (forall d. Data d => d -> u) -> ExceptState state e -> u

gmapM :: Monad m => (forall d. Data d => d -> m d) -> ExceptState state e -> m (ExceptState state e)

gmapMp :: MonadPlus m => (forall d. Data d => d -> m d) -> ExceptState state e -> m (ExceptState state e)

gmapMo :: MonadPlus m => (forall d. Data d => d -> m d) -> ExceptState state e -> m (ExceptState state e)

throwC :: Monad m => Cell (ExceptT e m) e arbitrary

wait :: Monad m => Double -> Cell (ExceptT () m) a a

throwIf :: Monad m => (a -> Bool) -> e -> Cell (ExceptT e m) a a

throwIf_ :: Monad m => (a -> Bool) -> Cell (ExceptT () m) a a

exceptC :: Monad m => Cell (ExceptT e m) (Either e a) a

When the incoming value is Right a, forward it. When it is Left e, throw it as an exception. Compare with except.
