Documentation
modifyReadTVar :: TVar a -> (a -> a) -> STM a Source #
Mutate the contents of a TVar and return the new value of the TVar (non-strict).
modifyReadTVar' :: TVar a -> (a -> a) -> STM a Source #
Mutate the contents of a TVar and return the new value of the TVar (strict).
modifyReadTVarIO :: TVar a -> (a -> a) -> IO a Source #
Mutate the contents of a TVar and return the new value of the TVar (non-strict).
modifyReadTVarIO' :: TVar a -> (a -> a) -> IO a Source #
Mutate the contents of a TVar and return the new value of the TVar (strict).
