fuzzcheck_mutators
This crate contains implementations of the Mutator trait of fuzzcheck.
Very few types are supported yet. (), bool, u8, Vec, and Option are
supported, and I have worked a bit on generic mutators that could work with
structs and enums, but there is still a lot of work to be done.
So you can fuzz-test types such as Vec<(Option<u8>, bool)> but not &str,
HashSet, i32, etc.
