Macro test_fuzz_runtime::auto_impl

macro_rules! auto_impl {
    ($ty : ty, $trait : path, $expr : expr) => { ... };
}

• ty - Type. When auto_impl! is used in the auto! macro, this should be just $ty.
• trait - Trait that ty may or may not implement.
• expr - Vector of values using trait, should ty implement it. In expr, T should be used as the name of the type, not $ty.
