fuzzcheck_serializer

This crate provides implementations of the Serializer trait defined by fuzzcheck.

There are currently two choices:

1. ByteSerializer serializes a Vec<u8> by directly writing the bits to a file. You can choose the file extension.
2. SerdeSerializer uses serde and serde_json to serialize any serde-Serializable type to a json file.

A catch is that SerdeSerializer is not directly defined in this crate. Instead, you must use the define_serde_serializer!() macro in the fuzz-target script to define it. Like this:

#[macro_use]
extern crate fuzzcheck_serializer;

extern crate serde;
extern crate serde_json; // serde_json MUST be visible
extern crate fuzzcheck; // fuzzcheck MUST be visible

use serde::{Serialize, Deserialize}; // Serializable and Deserializable MUST be visible

// Makes the SerdeSerializer available to fuzzcheck
define_serde_serializer!();

fn main() {
    // Will mutate values of type Vec<u8>
    let mutator = VecMutator<U8Mutator>::default();

    // Test inputs will be encoded with serde_json 
    let serializer = SerdeSerializer::<Vec<u8>>::default();

    // Launch the fuzzing process on the test function
    let _ = fuzzcheck::launch(test, mutator, serializer);
}
