Data.IORef.Lifted
Description
This is a wrapped version of Data.IORef with types
generalised from IO to all monads in MonadBase.
- data IORef a :: * -> *
- newIORef :: MonadBase IO m => a -> m (IORef a)
- readIORef :: MonadBase IO m => IORef a -> m a
- writeIORef :: MonadBase IO m => IORef a -> a -> m ()
- modifyIORef :: MonadBase IO m => IORef a -> (a -> a) -> m ()
- modifyIORef' :: MonadBase IO m => IORef a -> (a -> a) -> m ()
- atomicModifyIORef :: MonadBase IO m => IORef a -> (a -> (a, b)) -> m b
- atomicModifyIORef' :: MonadBase IO m => IORef a -> (a -> (a, b)) -> m b
- atomicWriteIORef :: MonadBase IO m => IORef a -> a -> m ()
- mkWeakIORef :: MonadBaseControl IO m => IORef a -> m () -> m (Weak (IORef a))
