How to get failed rules from .run method?

As I understood, the engine.run() method return all the successfull events. I know that we have a failure event, triggered per rule, where I could hook a callback, but that’s not what I’m looking for. What could be done to make engine.run() return booth, success and failed rules, an array of RuleResults maybe?

I’m using this, but it does not look good to me.

var failedRules = [];
engine1.on("failure", (event, almanac, ruleResult) => {
   failedRules.push(event);
});

@CacheControl This is a feature I’d like as well.

I’ll try to put together a PR this week.

Both failureEvents and failureResults are now returned by engine.run() in v6.0.0. See changelog
