Test.Aeson.Internal.RandomSamples

Description

Internal module, use at your own risk.

Synopsis

data RandomSamples a = RandomSamples {
- seed :: Int32
- samples :: [a]
}
setSeed :: Int -> Gen a -> Gen a
readSeed :: ByteString -> IO Int32
readSampleSize :: ByteString -> IO Int

Documentation

data RandomSamples a Source #

RandomSamples, using a seed allows you to replicate an arbitrary. By storing the seed and the samples (previously produced arbitraries), we can try to reproduce the same samples by generating the arbitraries with a seed.
