asyncEnd(event)

• 名称：tracing:${name}:asyncEnd

asyncEnd 事件表示异步函数返回的回调。事件数据在 asyncStart 事件之后不太可能发生变化，但查看回调完成的时间点可能会很有用。

【The asyncEnd event represents the callback of an asynchronous function returning. It's not likely event data will change after the asyncStart event, however it may be useful to see the point where the callback completes.】
