Cargo Fuzz

Use cargo-fuzz effectively to uncover input-handling bugs and improve Rust code robustness.

When to Use

• You need to fuzz-test Rust code paths that process untrusted input.
• You found a crash and want reproducible triage and fixes.

Workflow

1. Identify high-risk targets (parsers, decoders, protocol handlers).
2. Create fuzz target harness with clear entrypoint and constraints.
3. Seed useful corpus and configure sanitizers/timeouts.
4. Reproduce and minimize crashes for deterministic debugging.
5. Propose and validate fixes with regression and property checks.

Output

• Fuzz target setup plan
• Crash triage notes and fix strategy
• Regression checklist for hardened input handling
