mkCryptoULIDRandom :: CryptoRandomGen g => g -> Either GenError (ULIDRandom, g) Source #

Generate a ULIDRandom based on a cryptographically secure random number generator. See: https://hackage.haskell.org/package/crypto-api-0.13.3/docs/Crypto-Random.html

mkULIDRandom :: RandomGen g => g -> (ULIDRandom, g) Source #

Generate a ULIDRandom based on a standard random number generator. See: https://hackage.haskell.org/package/random-1.1/docs/System-Random.html

getULIDRandom :: IO ULIDRandom Source #

Note: The call to newStdGen splits the generator, so this is safe to call multiple times

Generate a ULID Random based on the global random number generator.
