同樣適用於[依賴項](tutorial/dependencies/index.md)。如果依賴項是一個標準的 `def` 函式，而不是 `async def`，那麼它在外部的執行緒池被運行。

### 子依賴項 { #sub-dependencies }

你可以擁有多個相互依賴的依賴項和[子依賴項](tutorial/dependencies/sub-dependencies.md)（作為函式定義的參數），其中一些可能是用 `async def` 宣告，也可能是用 `def` 宣告。它們仍然可以正常運作，用 `def` 定義的那些將會在外部的執行緒中呼叫（來自執行緒池），而不是被「等待」。

### 其他輔助函式 { #other-utility-functions }

你可以直接呼叫任何使用 `def` 或 `async def` 建立的其他輔助函式，FastAPI 不會影響你呼叫它們的方式。

这同样适用于[依赖](tutorial/dependencies/index.md)。如果一个依赖是标准的 `def` 函数而不是 `async def`，它将被运行在外部线程池中。

### 子依赖 { #sub-dependencies }

你可以拥有多个相互依赖的依赖以及[子依赖](tutorial/dependencies/sub-dependencies.md) （作为函数的参数），它们中的一些可能是通过 `async def` 声明，也可能是通过 `def` 声明。它们仍然可以正常工作，这些通过 `def` 声明的函数将会在外部线程中调用（来自线程池），而不是"被等待"。

### 其他函数 { #other-utility-functions }

你可直接调用通过 `def` 或 `async def` 创建的任何其他函数，FastAPI 不会影响你调用它们的方式。
