cargo-fuzz

separate

Sets up and runs cargo-fuzz, the standard fuzzing tool for Cargo-based Rust projects. Covers cargo fuzz init, the nightly toolchain requirement, fuzz_target! harnesses, Arbitrary-derived structured inputs, sanitizer options, cargo fuzz coverage, and reproducing a crash artifact. Use when fuzzing a Rust crate, writing a fuzz_target!, exercising unsafe blocks or FFI in Rust, or triaging a cargo fuzz crash.

When to use

• 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

When not to use

• non-Cargo projects
• multi-core fuzzing
• custom fuzzers
• research use cases
