Accessing Event on a Rule

Hello,

I'm working on a project in node that uses your rule engine, and I've noticed something that I can't understand.

The Rule class definition implements:
`export class Rule implements RuleProperties {
event: Event;
}`

But the Rule object uses
`ruleEvent: {}`

Trying to access a rule's events with `rule.event` returns nothing (as expected).

I've looked at the js code and there's a method `getEvent()`, that is not in index.d.ts.
What's the reason for all of this?
It seems it's impossible to access the event data.
