Description

Unboxed references

Based on the idea of Oleg Kiselyov (see http:www.haskell.orgpipermailhaskell-cafe2004-July006400.html)

Synopsis
newtype IOURef a = IOURef (IOSpecific2 MUVec a)
ioURefTc :: TyCon
newIOURef :: Unboxed a => a -> IO (IOURef a)
readIOURef :: Unboxed a => IOURef a -> IO a
writeIOURef :: Unboxed a => IOURef a -> a -> IO ()
modifyIOURef :: Unboxed a => IOURef a -> (a -> a) -> IO ()
newtype STURef s a = STURef (MUVec s a)
stURefTc :: TyCon
newSTURef :: Unboxed a => a -> ST s (STURef s a)
readSTURef :: Unboxed a => STURef s a -> ST s a
writeSTURef :: Unboxed a => STURef s a -> a -> ST s ()
modifySTURef :: Unboxed a => STURef s a -> (a -> a) -> ST s ()
