Pipes.RealTime

Pipes throttled by their own timestamps

timeCat :: MonadIO m => (a -> UTCTime) -> Pipe a a m r

Yield values at the absolute times given by their timestamps. Assumes that they arrive in ascending time order. Values with timestamps earlier than the starting time of the effect are discarded

timeCatDelayedBy :: MonadIO m => (a -> UTCTime) -> Double -> Pipe a a m r

Yield values at their absolute timesteps, but delay or advance their production by some time (given in seconds). Values with timestamps less than zero after adjustment are discarded

relativeTimeCat :: MonadIO m => (a -> Double) -> Pipe a a m r

Yield values some time after the effect is run, according to their relative timestamps. Assumes that values arrive in ascending time order. Values with negative relative timestamps are discarded

relativeTimeCatDelayedBy :: MonadIO m => (a -> Double) -> Double -> Pipe a a m r

Yield values at their timestamps, but delay by some time (given in seconds). Passing a negative delay advances the generator, discarding events happening before the effect

Pipes throttled by you

steadyCat :: MonadIO m => Double -> Pipe a a m r

Yield values at steady rate (Hz)

poissonCat :: MonadIO m => Double -> Pipe a a m r

Constant-rate Poisson process yielding values, randomized by IO

poissonCatConst :: MonadIO m => Double -> Pipe a a m r

Constant-rate Poisson process with a fixed seed - the same random every time

genPoissonCat :: MonadIO m => GenIO -> Double -> Pipe a a m r

Constant-rate Poisson process yielding values, seeded by you

catAtTimes :: MonadIO m => [UTCTime] -> Pipe a a m r

Yield values at a set of absolute times. Yield remaining values immediately if the time list becomes empty

catAtRelativeTimes :: MonadIO m => [Double] -> Pipe a a m r

Yield values at a set of times relative to the first received value. Yield remaining values immediately if the time list becomes empty
