inline fun <E : MessageEvent, M : Message.Element<M>> SimpleListenerBuilder<E>.matchMessage(messageKey: Message.Key<M>, require: Boolean = true, crossinline matcher: suspend EventListenerProcessingContext.(E, M, index: Int) -> Boolean)(source)

对一个消息事件 E 的消息元素中指定的类型进行校验。

buildSimpleListener(FooMessageEvent) {
  matchMessage(At, require = false) { event: FooMessageEvent, at: At, index: Int -> // this: EventListenerProcessingContext
     // ...

     at.target.literal != "123"
  }
