Sahip olduğu bir kaç özellik:

* Cidden etkileyici bir performans.
* WebSocket desteği.
* İşlem-içi arka plan görevleri.
* Başlatma ve kapatma olayları.
* HTTPX ile geliştirilmiş bir test istemcisi.
* CORS, GZip, Static Files ve Streaming cevapları desteği.
* Session ve çerez desteği.
* Kodun %100'ü test kapsamında.
* Kodun %100'ü tip belirteçleriyle desteklenmiştir.
* Yalnızca bir kaç zorunlu bağımlılığa sahip.

* Fitur lainnya (berkat Starlette) seperti:
    * **WebSocket**
    * Test yang sangat mudah berdasarkan HTTPX dan `pytest`
    * **CORS**
    * **Cookie Session**
    * ...dan lainnya.

## Performa

* Digər əlavə xüsusiyyətlər (Starlette sayəsində):
    * **WebSockets**
    * HTTPX və `pytest` sayəsində çox asan testlər
    * **CORS**
    * **Cookie Sessions**
    * ...və daha çoxu.

## Performans

   * access. Access time is reset by all cache read and write operations (including {@code
   * Cache.asMap().get(Object)} and {@code Cache.asMap().put(K, V)}), but not by {@code
   * containsKey(Object)}, nor by operations on the collection-views of {@link Cache#asMap}}. So,
   * for example, iterating through {@code Cache.asMap().entrySet()} does not reset access time for
   * the entries you retrieve.
   *

* **WebSocket**のサポート
* **GraphQL**のサポート
* プロセス内バックグラウンドタスク
* 起動およびシャットダウンイベント
* `httpx`に基づいて構築されたテストクライアント
* **CORS**、GZip、静的ファイル、ストリーミング応答
* **セッションとCookie**のサポート
* テストカバレッジ100%
* 型アノテーション100%のコードベース

## Pydanticの特徴

### Add some custom `tags`, `responses`, and `dependencies` { #add-some-custom-tags-responses-and-dependencies }

We are not adding the prefix `/items` nor the `tags=["items"]` to each *path operation* because we added them to the `APIRouter`.

    return new RegularImmutableMap<K, V>(hashTable, alternatingKeysAndValues, n);
  }

  /**
   * Returns a hash table for the specified keys and values, and ensures that neither keys nor
   * values are null. This method may update {@code alternatingKeysAndValues} if there are duplicate
   * keys. If so, the return value will indicate how many entries are still valid, and will also

 * }
 *
 * <p>This returns the string {@code "Harry; Ron; Hermione"}. Note that all input elements are
 * converted to strings using {@link Object#toString()} before being appended.
 *
 * <p>If neither {@link #skipNulls()} nor {@link #useForNull(String)} is specified, the joining
 * methods will throw {@link NullPointerException} if any given element is null.
 *

   *       equivalent(x, z)} is also true (<i>transitive</i> property)
   * </ul>
   *
   * <p>Note that all calls to {@code equivalent(x, y)} are expected to return the same result as
   * long as neither {@code x} nor {@code y} is modified.

  public final boolean equivalent(@Nullable T a, @Nullable T b) {
    if (a == b) {
      return true;
    }
    if (a == null || b == null) {
      return false;
    }

* Muchas funcionalidades extra (gracias a Starlette) como:
    * **WebSockets**
    * pruebas extremadamente fáciles basadas en HTTPX y `pytest`
    * **CORS**
    * **Sesiones de Cookies**
    * ...y más.
