Facts

Purpose: cargo-fuzz is a cargo subcommand for fuzzing with libFuzzer.github.com · 1 Oct 2026
Recommended use: The Rust Fuzz Book calls cargo-fuzz the recommended tool for fuzz testing Rust code.rust-fuzz.github.io · 1 Oct 2026
Fuzzer support: cargo-fuzz invokes a fuzzer rather than being a fuzzer itself, and currently supports libFuzzer through the libfuzzer-sys crate.rust-fuzz.github.io · 1 Oct 2026
Installation: The documented installation command is `cargo install cargo-fuzz`.rust-fuzz.github.io · 1 Oct 2026
Compiler requirement: The project requires the nightly Rust compiler because it uses the `-Z` compiler flag for address sanitization.rust-fuzz.github.io · 1 Oct 2026
Build requirement: A C++ compiler with C++11 support is required.rust-fuzz.github.io · 1 Oct 2026
Supported systems: The setup documentation lists x86-64 Linux, x86-64 macOS, Apple-Silicon macOS, and Windows with LLVM sanitizer support.rust-fuzz.github.io · 1 Oct 2026
Project setup: `cargo fuzz init` creates fuzzing files for a crate, and `cargo fuzz add <target>` creates a new fuzzing target.github.com · 1 Oct 2026
Fuzz execution: `cargo fuzz run <target>` runs a fuzzing target to find bugs.github.com · 1 Oct 2026
Input minimization: The tool provides `cargo fuzz tmin` to minimize a failing input and `cargo fuzz cmin` to minimize a corpus of input files.github.com · 1 Oct 2026
Coverage: `cargo fuzz coverage` generates source-based code coverage information and requires cargo-fuzz version 0.10.0 or newer.rust-fuzz.github.io · 1 Oct 2026
CI integration: The documentation provides a GitHub Actions workflow that installs cargo-fuzz, builds targets, runs them for a configured time, and uploads artifacts on failure.rust-fuzz.github.io · 1 Oct 2026
Windows integration: cargo-fuzz can fuzz Windows programs using MSVC AddressSanitizer.rust-fuzz.github.io · 1 Oct 2026
Licensing: cargo-fuzz is distributed under both the MIT license and Apache License Version 2.0.github.com · 1 Oct 2026
Package metadata: The Cargo package is version 0.13.2 and lists its authors as The rust-fuzz Project Developers.github.com · 1 Oct 2026
Platforms: The setup documentation lists x86-64 Linux, x86-64 macOS, Apple-Silicon macOS, and Windows support.rust-fuzz.github.io · 2 Oct 2026
Fuzz targets: cargo fuzz add creates a new fuzzing target and cargo fuzz run runs a fuzzing target to find bugs.github.com · 2 Oct 2026
Corpus minimization: cargo fuzz tmin minimizes a failing input and cargo fuzz cmin minimizes a corpus of input files.github.com · 2 Oct 2026
Structured fuzzing: The documentation supports structure-aware fuzzing through the fuzz_mutator! macro and the Arbitrary trait.rust-fuzz.github.io · 2 Oct 2026
Configuration: Fuzz targets can use Cargo feature options including --features, --no-default-features, and --all-features.rust-fuzz.github.io · 2 Oct 2026
Security status: GitHub reports that the repository has no security policy detected and no published security advisories.github.com · 2 Oct 2026
