• rQueue :: !(TBMQueue Event)

split :: Recorder -> Recorder

record :: forall a. Recorder -> String -> IO a -> IO a

record is a low level function for collecting timing information. Wrap each action of interest in a call to record.

record recorder $ threadDelay 1000000

record measures the elapsed time of the call, and catches HttpException in the case of failure. This means failures must be thrown if they are to be properly recorded.
