threadDelay is:exact

threadDelay :: Int -> IO ()

base Control.Concurrent GHC.Conc GHC.Conc.IO, protolude Protolude, ghc-internal GHC.Internal.Conc.IO, rebase Rebase.Prelude, context Context.Concurrent, verset Verset

Suspends the current thread for a given number of microseconds (GHC only). There is no guarantee that the thread will be rescheduled promptly when the delay has expired, but the thread will never continue to run earlier than specified. Be careful not to exceed maxBound :: Int, which on 32-bit machines is only 2147483647 μs, less than 36 minutes. Consider using Control.Concurrent.Thread.Delay.delay from unbounded-delays package.

threadDelay :: MonadIO m => Int -> m ()

unliftio UnliftIO.Concurrent, rio RIO

Lifted version of threadDelay.

threadDelay :: MonadBase IO m => Int -> m ()

lifted-base Control.Concurrent.Lifted

Generalized version of threadDelay.

threadDelay :: Int -> IO ()

base-prelude BasePrelude

Suspends the current thread for a given number of microseconds (GHC only). There is no guarantee that the thread will be rescheduled promptly when the delay has expired, but the thread will never continue to run earlier than specified.

threadDelay :: MonadConc m => Int -> m ()

concurrency Control.Monad.Conc.Class

Yields the current thread, and optionally suspends the current thread for a given number of microseconds. If suspended, there is no guarantee that the thread will be rescheduled promptly when the delay has expired, but the thread will never continue to run earlier than specified.

threadDelay _ = yield

threadDelay :: forall (unit :: Rat) m . (KnownDivRat unit Microsecond, MonadIO m) => Time unit -> m ()

o-clock Time.Units

Convenient version of threadDelay which takes any time-unit and operates in any MonadIO.

>>> threadDelay $ sec 2
>>> threadDelay (2 :: Time Second)
>>> threadDelay @Second 2
