And because the generated schema is from the <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md" class="external-link" target="_blank">OpenAPI</a> standard, there are many compatible tools.

                    return new StandardImplForwardingCollection<>(
                        new LinkedList<>(asList(elements)));
                  }
                })
            .named("ForwardingCollection[LinkedList] with standard implementations")
            .withFeatures(
                CollectionSize.ANY,
                CollectionFeature.ALLOWS_NULL_VALUES,
                CollectionFeature.GENERAL_PURPOSE)
            .createTestSuite());

The result of calling it is something that can be encoded with the Python standard <a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>.

It doesn't return a large `str` containing the data in JSON format (as a string). It returns a Python standard data structure (e.g. a `dict`) with values and sub-values that are all compatible with JSON.

## Automatische Konvertierung { #automatic-conversion }

`Header` bietet etwas zusätzliche Funktionalität im Vergleich zu `Path`, `Query` und `Cookie`.

Die meisten Standard-Header sind durch ein „Bindestrich“-Zeichen getrennt, auch bekannt als „Minus-Symbol“ (`-`).

Aber eine Variable wie `user-agent` ist in Python ungültig.

Если вы используете файл `requirements.txt`, вы можете указать версию следующим способом:

```txt
fastapi[standard]==0.112.0
```

это означает, что вы будете использовать именно версию `0.112.0`.

Или вы можете закрепить версию следующим способом:

```txt
fastapi[standard]>=0.112.0,<0.113.0
```

/// tip | 豆知識

`standard` を加えることで、Uvicornがインストールされ、いくつかの推奨される依存関係を利用するようになります。

これには、`asyncio` の高性能な完全互換品である `uvloop` が含まれ、並行処理のパフォーマンスが大幅に向上します。

// Usage:
//
//	go tool addr2line binary
//
// Addr2line reads hexadecimal addresses, one per line and with optional 0x prefix,
// from standard input. For each input address, addr2line prints two output lines,
// first the name of the function containing the address and second the file:line
// of the source code corresponding to that address.

En ajoutant `standard`, Uvicorn va installer et utiliser quelques dépendances supplémentaires recommandées.
