Package Information

Description:: 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.
