Lifted and unlifted classes and functions for the STM monad. To get started, just import Control.Concurrent.STM.Unlift. This is meant to be a drop-in replacement for Control.Concurrent.STM. This package provides functionality for the STM monad, which is highly analagous to the functionalty for the IO monad found in Control.Monad.IO.Class, Control.Monad.IO.Unlift, and UnliftIO.STM: MonadSTM is a copy of MonadIO modified for STM MonadUnliftSTM is a copy of MonadUnliftIO modified for STM Some functions found in Control.Concurrent.STM.Unlift are re-exported directly from UnliftIO.STM
