description = "A blazing-fast Rust rule engine with RETE algorithm, backward chaining inference, and GRL (Grule Rule Language) syntax. Features: forward/backward chaining, pattern matching, unification, O(1) rule indexing, TMS, expression evaluation, method calls, streaming with Redis state backend, watermarking, and custom functions. Production-ready for business rules, expert systems, real-time stream processing, and decision automation."
