### v1.1+

Version 1.1 added inline data, which will be placed after the metadata.

Therefore, the metadata is wrapped as a binary array for easy skipping.

Включая внешние библиотеки, также основанные на Pydantic, такие как <abbr title="Object-Relational Mapper">ORM</abbr>’ы, <abbr title="Object-Document Mapper">ODM</abbr>’ы для баз данных.

**FastAPI** 完全相容且基於 <a href="https://docs.pydantic.dev/" class="external-link" target="_blank"><strong>Pydantic</strong></a>。所以，你有其他 Pydantic 程式碼也能正常工作。

相容包括基於 Pydantic 的外部函式庫， 例如用於資料庫的 <abbr title="Object-Relational Mapper">ORM</abbr>s, <abbr title="Object-Document Mapper">ODM</abbr>s。

這也意味著在很多情況下，你可以把從請求中獲得的物件**直接傳到資料庫**，因為所有資料都會自動進行驗證。

反之亦然，在很多情況下，你也可以把從資料庫中獲取的物件**直接傳給客戶端**。

通過 **FastAPI** 你可以獲得所有 **Pydantic** 的特性（FastAPI 基於 Pydantic 做了所有的資料處理）：
