**FastAPI** はすべてPydanticをベースにしています。

## **FastAPI**での型ヒント

**FastAPI** はこれらの型ヒントを利用していくつかのことを行います。

**FastAPI** では型ヒントを使って型パラメータを宣言すると以下のものが得られます:

* **エディタサポート**.
* **型チェック**.

* `Field(index=True)` informa ao SQLModel que ele deve criar um **índice SQL** para essa coluna, o que permitirá buscas mais rápidas no banco de dados ao ler dados filtrados por essa coluna.
