**FastAPI** birkaç şey yapmak için bu tür tip belirteçlerinden faydalanır.

**FastAPI** ile parametre tiplerini bildirirsiniz ve şunları elde edersiniz:

* **Editor desteği**.
* **Tip kontrolü**.

...ve **FastAPI** aynı belirteçleri şunlar için de kullanıyor:

* **Gereksinimleri tanımlama**:  request path parameters, query parameters, headers, bodies, dependencies, ve benzeri gereksinimlerden

     * {@code Closeable} with a method reference like {@code cursor::close}.
     *
     * <p>Note that this method is still binary-compatible between flavors because the erasure of
     * its parameter type is {@code Object}, not {@code AutoCloseable} or {@code Closeable}.
     *
     * @param closeable the object to be closed (see notes above)
     * @param closingExecutor the object will be closed on this executor

- Support inflight_events metric in the scheduler for QueueingHint. ([#127052](https://github.com/kubernetes/kubernetes/pull/127052), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]
- Support specifying a custom network parameter when running e2e-node-tests with the remote option. ([#127574](https://github.com/kubernetes/kubernetes/pull/127574), [@bouaouda-achraf](https://github.com/bouaouda-achraf)) [SIG Node and Testing]

Vous devez vous assurer qu'il est unique pour chaque opération.

- Fix a panic when using invalid output format in kubectl create secret command ([#107346](https://github.com/kubernetes/kubernetes/pull/107346), [@rikatz](https://github.com/rikatz)) [SIG CLI]
- Fix: azuredisk parameter lowercase translation issue ([#107429](https://github.com/kubernetes/kubernetes/pull/107429), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]

- Deprecated the `--cloud-provider` and `--cloud-config` CLI parameters in kube-apiserver.
  These parameters will be removed in a future release. ([#120903](https://github.com/kubernetes/kubernetes/pull/120903), [@dims](https://github.com/dims)) [SIG API Machinery]

- Kube-log-runner: Added the `-log-file-size` parameter to rotate log output into a new file once it reached a certain size. Introduced `-log-file-age` to enable automatic removal of old output files, and `-flush-interval` to support periodic flushing. ([#127667](https://github.com/kubernetes/kubernetes/pull/127667),...

* Entrambi i _paths_ accettano`GET` operations (conosciuti anche come <abbr title="metodi HTTP">HTTP _methods_</abbr>).
* Il _path_ `/items/{item_id}` ha un _path parameter_ `item_id` che deve essere un `int`.
* Il _path_ `/items/{item_id}` ha una `str` _query parameter_ `q`.

### Documentazione interattiva dell'API

  fun emptyCache(parameters: Pair<FileSystem, Boolean>) {
    setUp(parameters.first, parameters.second)
    cache.close()
    assertJournalEquals()
  }

  @ParameterizedTest
  @ArgumentsSource(FileSystemParamProvider::class)
  fun recoverFromInitializationFailure(parameters: Pair<FileSystem, Boolean>) {
    setUp(parameters.first, parameters.second)

Donc :

```Python
q: Union[str, None] = Query(default=None)
```

... rend le paramètre optionnel, et est donc équivalent à :

```Python
q: Union[str, None] = None
```

Mais déclare explicitement `q` comme étant un paramètre de requête.
