// Exit conditions:
	//
	// 1. If a writer.write() returns false, select loop below exits and
	// closes `doneCh` to indicate to caller to also exit.
	//
	// 2. If caller (Evaluate()) has an error, it sends an error
	// message and waits for this go-routine to quit in
	// FinishWithError()
	//
	// 3. If caller is done, it waits for this go-routine to exit
	// in Finish()

* busca el módulo `dependencies` (un archivo imaginario en `app/routers/dependencies.py`)...
* y de él, importa la función `get_token_header`.

Pero ese archivo no existe, nuestras dependencias están en un archivo en `app/dependencies.py`.

Recuerda cómo se ve nuestra estructura de aplicación/archivo:

You can declare the type used for the response by annotating the *path operation function* **return type**.

You can use **type annotations** the same way you would for input data in function **parameters**, you can use Pydantic models, lists, dictionaries, scalar values like integers, booleans, etc.

{* ../../docs_src/response_model/tutorial001_01_py310.py hl[16,21] *}

FastAPI will use this return type to:

* **Validate** the returned data.

## Déprécier des paramètres

Disons que vous ne vouliez plus utiliser ce paramètre désormais.

Il faut qu'il continue à exister pendant un certain temps car vos clients l'utilisent, mais vous voulez que la documentation mentionne clairement que ce paramètre est <abbr title="obsolète, recommandé de ne pas l'utiliser">déprécié</abbr>.

		if isErrBucketNotFound(err) {
			return batchExpireJobError{
				Code:           "NoSuchSourceBucket",
				Description:    "The specified source bucket does not exist",
				HTTPStatusCode: http.StatusNotFound,
			}
		}
		return err
	}

	if len(r.Rules) > maxBatchRules {
		return batchExpireJobError{
			Code:           "InvalidArgument",

	err := os.Remove(filepath.Join(store.directory, key.String()))

	// Delete as entry no matter the result
	delete(store.entries, key.String())

	return err
}

// List - lists all files registered in the store.
func (store *QueueStore[_]) List() (keys []Key) {

# 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
```

	if err != nil {
		if isErrBucketNotFound(err) {
			return batchReplicationJobError{
				Code:           "NoSuchSourceBucket",
				Description:    fmt.Sprintf("The specified bucket %s does not exist", localBkt),
				HTTPStatusCode: http.StatusNotFound,
			}
		}
		return err
	}

	if err := r.Source.Type.Validate(); err != nil {
		return err
	}

```

```sh
mc idp ldap policy detach myminio mypolicy ----group='cn=projectx,ou=groups,ou=hwengg,dc=min,dc=io'
```


Note that the commands above attempt to validate if the given entity (user or group) exist in the LDAP directory and return an error if they are not found.
