Why has it taken me so long to find this? I'm excited to try out fuzzcheck on the new
sled.rs inline Node binary format. It combines fuzzing with property testing in a way that may avoid the performance issues I've hit with using quickcheck+libfuzzer in the past.
I've published an update to fuzzcheck-rs! What's new:
1. It is much faster
2. Mutators are efficiently composable (e.g. given a Vec mutator, it's trivial to create one for Vec<Vec<_>>)
3. New inputs are generated from existing ones by mutating them in-place, with zero allocation
