Docker Hubは 多くのツールや環境、データベース、アプリケーションに対応している予め作成された**公式のコンテナ・イメージ**をパブリックに提供しています。

例えば、公式イメージの1つに<a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python Image</a>があります。

その他にも、データベースなどさまざまなイメージがあります：

* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>

            c[j++] = HEX_DIGITS[src[i] & 0x0F];
        }
        return new String( c );
    }

/** 
 * This is the same as {@link jcifs.smb1.util.Hexdump#toHexString(int val, int
 * size)} but provides a more practical form when trying to avoid {@link
 * java.lang.String} concatenation and {@link java.lang.StringBuffer}.
 */ 
    public static void toHexChars( int val, char dst[], int dstIndex, int size ) {
        while( size > 0 ) {

# Body - Обновления

## Полное обновление с помощью `PUT`

Для полного обновления элемента можно воспользоваться операцией <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a>.

Вы можете использовать функцию `jsonable_encoder` для преобразования входных данных в JSON, так как нередки случаи, когда работать можно только с простыми типами данных (например, для хранения в NoSQL-базе данных).

/// info | "Informação"

`status_code` também pode receber um `IntEnum`, como o do Python <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

///

Dessa forma:

* Este código de status será retornado na resposta.
* Será documentado como tal no esquema OpenAPI (e, portanto, nas interfaces do usuário):

import com.google.common.collect.ImmutableList;
import com.google.errorprone.annotations.CanIgnoreReturnValue;

/**
 * Standard implementation of {@link MutableNetwork} that supports both directed and undirected
 * graphs. Instances of this class should be constructed with {@link NetworkBuilder}.
 *
 * <p>Time complexities for mutation methods are all O(1) except for {@code removeNode(N node)},

  }

  /** Test that giving a null 'safeChars' string causes a {@link NullPointerException}. */
  public void testBadArguments_null() {
    assertThrows(NullPointerException.class, () -> new PercentEscaper(null, false));
  }

  /**
   * Tests that specifying any alphanumeric characters as 'safe' causes an {@link
   * IllegalArgumentException}.
   */
  public void testBadArguments_badchars() {

Para produção você usaria `fastapi run` no lugar. 🚀

Internamente, **FastAPI CLI** usa <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, um servidor ASGI de alta performance e pronto para produção. 😎

## `fastapi dev`

Quando você roda `fastapi dev`, isso vai executar em modo de desenvolvimento.

# "TFCI_MACOS_INSTALL_BAZELISK_ENABLE" is used to decide if we need to install
# Bazelisk manually. We enable this for macOS x86 builds as those VMs do not
