   * <p>If no default value is desired (and the caller instead wants a {@link
   * NoSuchElementException} to be thrown), it is recommended that {@code
   * iterable.iterator().next()} is used instead.
   *
   * <p>To get the only element in a single-element {@code Iterable}, consider using {@link
   * #getOnlyElement(Iterable)} or {@link #getOnlyElement(Iterable, Object)} instead.

在長時間尋找並測試多種不同替代方案後，APIStar 是最好的可用選擇。

當 APIStar 不再作為伺服器存在，而 Starlette 誕生並成為更好的基礎時，這成為打造 **FastAPI** 的最後一個靈感。

我將 **FastAPI** 視為 APIStar 的「精神繼承者」，同時基於所有這些先前工具的經驗，改進並擴增了功能、型別系統與其他部分。

Pydantic 是基於 Python 型別提示，定義資料驗證、序列化與文件（使用 JSON Schema）的函式庫。

這讓它非常直覺。
