Kind of, `cargo fuzz` doesn't know how to format your code, only the fuzz target (written by the user) does, since `cargo-fuzz` is unaware of the types being used. Due to the way libFuzzer works -- it replaces your main function -- we can't add another code path that just loads the string from a specified file and formats it because no matter what libFuzzer will still be run.
