#### `HeroPublic` - 公共*数据模型* { #heropublic-the-public-data-model }

接下来，我们创建一个 `HeroPublic` 模型，这是将**返回**给 API 客户端的模型。

它包含与 `HeroBase` 相同的字段，因此不会包括 `secret_name`。

终于，我们英雄的身份得到了保护！🥷

    connection.setFixedLengthStreamingMode(1024 * 1024 * 1024) // 1 GB
    connection.connect()
    val out = connection.outputStream
    val data = ByteArray(1024 * 1024)
    var i = 0
    while (i < 1024) {
      try {
        out.write(data)
        out.flush()
        if (i == 513) {
          // pause slightly after halfway to make result more predictable
          Thread.sleep(100)
        }

#### Случайный элемент { #a-random-item }

С помощью `data.items()` мы получаем <dfn title="Объект, по которому можно итерироваться циклом for, например список, множество и т.п.">итерируемый объект</dfn> с кортежами, содержащими ключ и значение для каждого элемента словаря.

Мы превращаем этот итерируемый объект в обычный `list` через `list(data.items())`.

### typing 模块 { #typing-module }

在一些额外的用例中，你可能需要从标准库的 `typing` 模块导入内容。比如当你想声明“任意类型”时，可以使用 `typing` 中的 `Any`：

```python
from typing import Any


def some_function(data: Any):
    print(data)
```

### 泛型类型 { #generic-types }

有些类型可以在方括号中接收“类型参数”（type parameters），用于声明其内部值的类型。比如“字符串列表”可以写为 `list[str]`。

这些能接收类型参数的类型称为“泛型类型”（Generic types）或“泛型”（Generics）。

 *  Fix: Don't lose HTTP/2 flow control bytes when incoming data races with a stream close. If this
    happened enough then eventually the connection would stall.

 *  Fix: Acknowledge and apply inbound HTTP/2 settings atomically. Previously we had a race where we
