lucascs@protonmail.com Lucas C.S. cargo-fuzz is the cargo subcommand for fuzzing a Rust crate with libFuzzer. It generates and maintains the fuzz target boilerplate, builds the target with the sanitizer and coverage instrumentation libFuzzer needs, and manages the corpus. Note that running a fuzz target requires a nightly toolchain, because the instrumentation is driven by unstable compiler flags. https://github.com/rust-fuzz/cargo-fuzz/issues rust-fuzz/cargo-fuzz
