任何类型都有合理的**默认值**，任何和地方都有可选配置。所有的参数被微调，来满足你的需求，定义成你需要的 API。

但是默认情况下，一切都能**“顺利工作”**。

### 验证 { #validation }

* 校验大部分（甚至所有？）的 Python **数据类型**，包括：
    * JSON 对象 (`dict`)。
    * JSON 数组 (`list`) 定义成员类型。
    * 字符串 (`str`) 字段，定义最小或最大长度。
    * 数字 (`int`, `float`) 有最大值和最小值，等等。

* 校验外来类型，比如：
    * URL。
    * Email。
    * UUID。
    * ...及其他。

所有的校验都由完善且强大的 **Pydantic** 处理。

   * nulls in the stream. This means that the method can safely be used with a stream that contains
   * nulls as long as the *last* element is *not* null.
   *
   * (To "go out of its way," the method tracks a `set` bit so that it can distinguish "the final
   * split has a last element of null, so throw NPE" from "the final split was empty, so look for an
   * element in the prior one.")
