cargo-fuzz

cargo-fuzz is the de facto choice for fuzzing Rust projects when using Cargo. It uses libFuzzer as the backend and provides a convenient Cargo subcommand that automatically enables relevant compilation flags for your Rust project, including support for sanitizers like AddressSanitizer.

When to Use

cargo-fuzz is currently the primary and most mature fuzzing solution for Rust projects using Cargo.

Choose cargo-fuzz when:

• Your project uses Cargo (required)
• You want simple, quick setup with minimal configuration
• You need integrated sanitizer support
• You're fuzzing Rust code with or without unsafe blocks
