Arbitrary data #22

Closed nagisa closed 7 years ago

nagisa commented 7 years ago

Might be nice to have have something similar to quickcheck’s Arbitrary trait, so instead of always taking &[u8], we could make it take anything that implements some Arbitrary trait and provide a number of impls for such trait. (e.g. to fuzz with a String, to fuzz with an array of numbers of some type, to fuzz with something else)

Here the original &[u8] would be used as a source of “randomness”.
