Documentation

getTime :: IO Double Source #

time :: MonadIO m => m a -> m (Double, a) Source #

Measure how long action took, in seconds along with its result

time_ :: MonadIO m => m a -> m Double Source #

Just measure how long action takes, discard its result

timeEx :: (MonadCatch m, MonadIO m) => m a -> m (Double, Either SomeException a) Source #

Measure how long action took, even if they fail
