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.

首先比较 Rule 类定义、ruleEvent 对象、JavaScript getEvent() 方法，以及 issue 中提到的 index.d.ts 声明。追踪事件数据的表示和公开方式，然后验证公开行为与类型声明是否一致；当访问事件数据的受支持方式清晰明确且得到准确表示时，即视为完成。
