## Context Managers

### What are "Context Managers"

"Context Managers" are any of those Python objects that you can use in a `with` statement.

## Feature implementation

Release managers will continue to have a final say in what gets merged or not, unless directed by the TOC. See the next
section if the implementation is done, but a bug is being addressed.

* Any code that changes feature functionality must be done within 2 weeks of the release branch cutting. Even then it is
 at the discretion of the release managers if PRs will be accepted and merged into the release branch.

# yieldを持つ依存関係

FastAPIは、いくつかの<abbr title='時々"exit"、"cleanup"、"teardown"、"close"、"context managers"、 ...のように呼ばれる'>終了後の追加のステップ</abbr>を行う依存関係をサポートしています。

これを行うには、`return`の代わりに`yield`を使い、その後に追加のステップを書きます。

/// tip | "豆知識"

`yield`は必ず一度だけ使用するようにしてください。

///

/// info | "情報"

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```

# 使用yield的依赖项

FastAPI支持在完成后执行一些<abbr title='有时也被称为"退出"("exit")，"清理"("cleanup")，"拆卸"("teardown")，"关闭"("close")，"上下文管理器"("context managers")。 ...'>额外步骤</abbr>的依赖项.

为此，你需要使用 `yield` 而不是 `return`，然后再编写这些额外的步骤（代码）。

/// tip | 提示

确保在每个依赖中只使用一次 `yield`。

///

/// note | "技术细节"

任何一个可以与以下内容一起使用的函数：

# Зависимости с yield

FastAPI поддерживает зависимости, которые выполняют некоторые <abbr title='также известные как "exit", "cleanup", "teardown", "close", "context managers", ...'>дополнительные действия после завершения работы</abbr>.

Для этого используйте `yield` вместо `return`, а дополнительный код напишите после него.

/// tip | "Подсказка"

Обязательно используйте `yield` один-единственный раз.

///

/// note | "Технические детали"

Wenn Sie gerade erst mit **FastAPI** beginnen, möchten Sie das vielleicht vorerst überspringen.

In Python können Sie Kontextmanager erstellen, indem Sie <a href="https://docs.python.org/3/reference/datamodel.html#context-managers" class="external-link" target="_blank">eine Klasse mit zwei Methoden erzeugen: `__enter__()` und `__exit__()`</a>.

Se você está apenas iniciando com o **FastAPI** você pode querer pular isso por enquanto.

This document outlines the concerns of a general plugin manager that would be used in conjunction with any Plexus-based application. The following outlined concerns are an attempt to describe what a plugin manager would need to do for Maven and for Nexus.
