Data.IORef.Extra
Description
This module extends Data.IORef with operations forcing the value written to the IORef. Some of these functions are available in later versions of GHC, but not all.
Synopsis
- module Data.IORef
- modifyIORef' :: IORef a -> (a -> a) -> IO ()
- writeIORef' :: IORef a -> a -> IO ()
- atomicModifyIORef' :: IORef a -> (a -> (a, b)) -> IO b
- atomicWriteIORef :: IORef a -> a -> IO ()
- atomicWriteIORef' :: IORef a -> a -> IO ()
Documentation
module Data.IORef
modifyIORef' :: IORef a -> (a -> a) -> IO () #
Strict version of modifyIORef
Since: base-4.6.0.0
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.
Since: base-4.6.0.0
atomicWriteIORef :: IORef a -> a -> IO () #
Variant of writeIORef with the "barrier to reordering" property that
atomicModifyIORef has.
Since: base-4.6.0.0
atomicWriteIORef' :: IORef a -> a -> IO () Source #
Evaluates the value before calling atomicWriteIORef.
