Оскільки Pydantic серіалізує це на боці **Rust**, ви отримаєте значно вищу **продуктивність**, ніж якби не оголошували тип повернення.

### Не-async *функції операцій шляху* { #non-async-path-operation-functions }

Ви також можете використовувати звичайні функції `def` (без `async`) і використовувати `yield` так само.

FastAPI подбає про коректне виконання, щоб воно не блокувало цикл подій.

```

### Things to know

- Fields such as `version` and `pools` are mandatory, however all other fields are optional.
- Each pool expects a minimum of 2 nodes per pool, and unique non-repeating hosts for each argument.
- Each pool expects each host in this pool has the same number of drives specified as any other host.

        // Name all the non-root projects after their path so that paths get grouped together when imported into eclipse.
        if (project.getPath().equals(":") == false) {
            eclipseProject.setName(project.getPath());

## 可选文件上传 { #optional-file-upload }

你可以通过使用标准类型注解并将 `None` 作为默认值的方式将一个文件参数设为可选:

{* ../../docs_src/request_files/tutorial001_02_an_py310.py hl[9,17] *}

## 带有额外元数据的 `UploadFile` { #uploadfile-with-additional-metadata }

你也可以将 `File()` 与 `UploadFile` 一起使用，例如，设置额外的元数据:
