A Rust library implementing an execution engine for Wireshark-like filter expressions, including parsing, compilation, and fast evaluation. It powers Cloudflare's firewall rules and can be embedded in other products.

Use cases

• evaluate wireshark-style filter expressions in my application
• embed a fast packet filter DSL in a Rust service
• compile and run firewall rule expressions
• parse network filter syntax into an AST
• build custom filtering rules for traffic matching

When to choose

• you need Wireshark-compatible filter syntax with high-performance evaluation
• you want a memory-safe Rust engine to embed in other languages
• you're building firewall or traffic-matching rule engines

When to avoid

• you need a full packet capture or analysis tool rather than a filter engine
• you want a ready-made firewall application with a UI
• your filters are simple enough for plain boolean logic without a DSL
