## 其他返回类型注解 { #other-return-type-annotations }

有些情况下你会返回一些不是有效 Pydantic 字段的内容，并在函数上做了相应注解，只是为了获得工具链（编辑器、mypy 等）的支持。

### 直接返回 Response { #return-a-response-directly }

最常见的情况是[直接返回 Response，详见进阶文档](../advanced/response-directly.md)。

{* ../../docs_src/response_model/tutorial003_02_py310.py hl[8,10:11] *}

这个简单场景 FastAPI 会自动处理，因为返回类型注解是 `Response`（或其子类）。

//go:generate msgp -file $GOFILE -unexported

type listPathOptions struct {
	// ID of the listing.
	// This will be used to persist the list.
	ID string

	// Bucket of the listing.
	Bucket string

	// Directory inside the bucket.
	// When unset listPath will set this based on Prefix
	BaseDir string

	// Scan/return only content with prefix.
	Prefix string

 * <p>The common ways to get an instance of {@code Ordering} are:
 *
 * <ul>
 *   <li>Subclass it and implement {@link #compare} instead of implementing {@link Comparator}
 *       directly
 *   <li>Pass a <i>pre-existing</i> {@link Comparator} instance to {@link #from(Comparator)}
 *   <li>Use the natural ordering, {@link Ordering#natural}
