What is the best rust-based rules engine?

Hello,

I am looking for a very fast rules engine. Are there any recommendations for which to use. Ideally, I would like an engine that does not require a restart/build to add rules.

Thanks.

What do you mean by rule engine?

Something like https://docs.rs/json-rules-engine/latest/json_rules_engine/# or drools. A way to build a set of rules, and then run them on multiple data items.
