Documentation

sleep :: MonadConc m => Double -> m () Source #

sleep for x seconds

keepOpen :: MonadConc m => Cont m (Emitter (STM m) a) Source #

keeping a box open sometimes needs a long running emitter

delayTimed :: (MonadConc m, MonadIO m) => Stream (Of (NominalDiffTime, a)) m () -> Stream (Of a) m () Source #

a stream with suggested delays. DiffTime is the length of time to wait since the start of the stream > delayTimed (S.each (zip (fromIntegral $ [1..10]) [1..10])) |> S.print

data Stamped a Source #

adding a time stamp todo: how to do this properly?
