fuzzcheck_mutators

This crate contains implementations of the Mutator trait of fuzzcheck.

Very few types are supported yet. (), bool, u8-u64, i8-i64 Vec, and Option are supported, as well as arbitrary structs and enums through the procedural macros provided by fuzzcheck_mutators_derive. But other types of the standard library such as String, HashMap/Set, etc. do not have default mutators yet.

So you can fuzz-test types such as Vec<(Option<u8>, bool)> but not &str, HashSet, etc.
