lifted-async Control.Concurrent.Async.Lifted.Safe A version of wait that can be used inside an STM transaction.
unsafeLastM :: (Monad m, Source r e) => Vector r e -> m emassiv Data.Massiv.Array.Unsafe No documentation available.
lastM :: (Source r e, MonadThrow m) => Vector r e -> m emassiv Data.Massiv.Vector O(1) - Get the last element of a Source vector. Related: last', unsnocM Throws Exceptions: SizeEmptyException
Examples
>>> lastM (Ix1 10 ... 10000000000000) 10000000000000 >>> lastM (Ix1 10 ... 10000000000000) :: Maybe Int Just 10000000000000 >>> either show (const "") $ lastM (fromList Seq [] :: Array P Ix1 Int) "SizeEmptyException: (Sz1 0) corresponds to an empty array"

protolude Protolude The thread is waiting to retry an STM transaction, but there are no other references to any TVars involved, so it can't ever continue.
BlockedIndefinitelyOnSTM :: BlockedIndefinitelyOnSTMprotolude Protolude No documentation available.
threadWaitReadSTM :: Fd -> IO (STM (), IO ())protolude Protolude Returns an STM action that can be used to wait for data to read from a file descriptor. The second returned value is an IO action that can be used to deregister interest in the file descriptor.
threadWaitWriteSTM :: Fd -> IO (STM (), IO ())protolude Protolude Returns an STM action that can be used to wait until data can be written to a file descriptor. The second returned value is an IO action that can be used to deregister interest in the file descriptor.

reflex Data.FastMutableIntMap A FastMutableIntMap holds a map of values of type a and allows low-overhead modifications via IO. Operations on FastMutableIntMap run in IO.
