DAOS API 函数可以在阻塞或非阻塞模式下使用。 这是通过传递给每个 API 调用的指向 DAOS 事件的指针来确定的：如果 NULL 表示操作将被阻塞。 ...

队列中的代码，通常使用 Future 向 EventQueue加入时间，也可以使用 async 和 await 向 EventQueue 加入事件。...总结：Dart 中事件的执行顺序：Main > MicroTask > EventQueue。 如图： ?...此时我们的 EventQueue 中还有 f5，和在 f4 中添加的新的Future。 所以我们的最终结果就是：8，1，7，4，6，3，5，2。...重要要在脑海里有一个 EventQueue 的队列模型，牢记先进先出。...没关系，很正常，看我慢慢道来： 分析： 根据 Main > MicroTask > EventQueue。我们首先会得到输出结果：12，1，11。
