module Data.IORef
modifyIORef' :: IORef a -> (a -> a) -> IO ()
Strict version of modifyIORef
writeIORef' :: IORef a -> a -> IO ()Source
Evaluates the value before calling writeIORef
.
atomicModifyIORef' :: IORef a -> (a -> (a, b)) -> IO b
Strict version of atomicModifyIORef
. This forces both the value stored
in the IORef
as well as the value returned.
atomicWriteIORef :: IORef a -> a -> IO ()
Variant of writeIORef
with the "barrier to reordering" property that
atomicModifyIORef
has.
atomicWriteIORef' :: IORef a -> a -> IO ()Source
Evaluates the value before calling atomicWriteIORef
.
