* Optional<T>}. Casting either of the above example {@code Optional} instances to {@code
   * Optional<Number>} (where {@code Number} is the desired output type) solves the problem:

   * <pre>{@code
   * Optional<Number> optionalInt = (Optional) getSomeOptionalInt();
   * Number value = optionalInt.or(0.5); // fine

接下来，它 🤖 完成第一个任务（比如是我们的"慢文件"📝) 并继续与之相关的一切。

这个"等待其他事情"通常指的是一些相对较慢（与处理器和 RAM 存储器的速度相比）的 <abbr title="Input and Output">I/O</abbr> 操作，比如说：

* 通过网络发送来自客户端的数据
* 客户端接收来自网络中的数据
* 磁盘中要由系统读取并提供给程序的文件的内容
* 程序提供给系统的要写入磁盘的内容
* 一个 API 的远程调用
* 一个数据库操作，直到完成
* 一个数据库查询，直到返回结果
* 等等.

这个执行的时间大多是在等待 <abbr title="Input and Output">I/O</abbr> 操作，因此它们被叫做 "I/O 密集型" 操作。

它被称为"异步"的原因是因为计算机/程序不必与慢任务"同步"，去等待任务完成的确切时刻，而在此期间不做任何事情直到能够获取任务结果才继续工作。

(cerca de 100 nanosegundos), por favor observe que no **FastAPI** o efeito pode ser bem o oposto. Nesses casos, é melhor usar `async def` a menos que suas *funções de operação de rota* utilizem código que performem bloqueamento <abbr title="Input/Output: disco lendo ou escrevendo, comunicações de rede.">IO</abbr>.

Ainda, em ambas as situações, as chances são que o **FastAPI** será [ainda mais rápido](index.md#performance){.internal-link target=_blank} do que (ou ao menos comparável a)...
