Control.Monad.Trans.Alarm
Description
Monad transformer for managing an alarm clock.
- data AlarmT m a
- runAlarmT :: (TimeUnit t, MonadIO m, MonadMask m) => AlarmT m a -> t -> m a
- startAlarm :: MonadIO m => AlarmT m ()
- startAlarm' :: (TimeUnit t, MonadIO m) => t -> AlarmT m ()
- stopAlarm :: MonadIO m => AlarmT m ()
- restartAlarm :: MonadIO m => AlarmT m ()
- restartAlarm' :: (TimeUnit t, MonadIO m) => t -> AlarmT m ()
- alarm :: (MonadIO m, MonadCatch m) => m a -> AlarmT m (Maybe a)
- alarm' :: (TimeUnit t, MonadIO m, MonadCatch m) => t -> m a -> AlarmT m (Maybe a)
