- random :: Natural -> IO ByteString
- randomGen :: GenIO -> Natural -> IO ByteString
Documentation
Arguments
| :: Natural | Length of the result bytestring in bytes |
| -> IO ByteString |
Generate a random bytestring of length n. The PRNG is seeded from the system randomness source.
ioProperty $ ((fromIntegral n ===) . B.length) <$> random n
n > 4 ==> ioProperty $ (/=) <$> random n <*> random n
Arguments
| :: GenIO | PRNG |
