   > For the fuzzing though, I'm wondering if we considered using something 
more robust like [AFL](https://rust-fuzz.github.io/book/afl.html). Afl does 
coverage guided fuzzing which should be more effective at finding weird edge 
cases than just flipping bits at random, because it can use code coverage to 
determine which paths to take when mutating test cases. It also gets us test 
minimization for free
   
   I recommend we file another ticket to look into a more robust / automated 
framework for fuzzing. It applies to more than just variant and would make a 
nice addition to this crate I think (though I also think it will be a non 
trivial thing to setup, but I haven't actually tried it)
