Summary
- Requires nightly Rust toolchain and works best with library crate structure; automatically enables AddressSanitizer by default for memory error detection
- Provides cargo fuzz init scaffolding, harness templates, and corpus/artifact management; supports structure-aware fuzzing via the arbitrary crate for type-driven input generation
- Includes coverage analysis integration, dictionary support for format-aware fuzzing, and libFuzzer option passthrough for timeout, input size, and other runtime controls
- Disables sanitizers with --sanitizer none for 2x performance boost on safe Rust code; re-executes crashes and corpus entries for regression testing
