atomic-modify-general: Generalizations of atomicModifyIORef
base
provides
atomicModifyIORef :: IORef a -> (a -> (a, b)) -> IO b atomicModifyIORef2 :: IORef a -> (a -> (a, b)) -> IO (a, (a, b))
to modify the value in an IORef
and return a result (and, in the
case of atomicModifyIORef2
, also return the old value).
In Data.IORef.AtomicModify, we generalize this from pairs to arbitrary
types for which the user can provide a function to extract the new
value to store in the IORef
.
In Data.IORef.AtomicModify.Generic, we offer a faster but more restricted
version taking advantage of the fact that the primop used to implement
atomicModifyIORef2
actually works for somewhat more general record types
than atomicModifyIORef2
accepts.
