public void testStringConverterSerialization() {
    SerializableTester.reserializeAndAssert(Longs.stringConverter());
  }

  public void testToArray() {
    // need explicit type parameter to avoid javac warning!?
    List<Long> none = Arrays.<Long>asList();
    assertThat(Longs.toArray(none)).isEqualTo(EMPTY);

    List<Long> one = Arrays.asList((long) 1);
    assertThat(Longs.toArray(one)).isEqualTo(ARRAY1);

Eso ya debería tener más sentido ahora. ✨

Todo eso es lo que impulsa FastAPI (a través de Starlette) y lo que hace que tenga un rendimiento tan impresionante.

Estos son detalles muy técnicos de cómo **FastAPI** funciona a muy bajo nivel.

That should make more sense now. ✨

All that is what powers FastAPI (through Starlette) and what makes it have such an impressive performance.

## Very Technical Details

    **Warning:** Avoid `Level.HEADERS` and `Level.BODY` in production because
    they could leak passwords and other authentication credentials to insecure
    logs.

 * or an explicit {@link Comparator}. In all cases, this implementation uses {@link
 * Comparable#compareTo} or {@link Comparator#compare} instead of {@link Object#equals} to determine
 * equivalence of instances.
 *
 * <p><b>Warning:</b> The comparison must be <i>consistent with equals</i> as explained by the
 * {@link Comparable} class specification. Otherwise, the resulting multiset will violate the {@link

### Other (Cleanup or Flake)

For new clusters if you have not configured the cgroup driver explicitly you might get a failure in the `kubelet` on driver mismatch (kubeadm clusters should be using the `systemd` driver). Also remove the `IsDockerSystemdCheck` preflight check (warning) that checks if the Docker cgroup driver is set to `systemd`. Ideally such detection / coordination should be on the side of CRI implementers and the kubelet (tracked [here](https://github.com/kubernetes/kubernetes/issues/99808)). Please see the ...

 * encoding and decoding behavior, use configuration methods to obtain a new encoding with modified
 * behavior:
 *
 * <pre>{@code
 * BaseEncoding.base16().lowerCase().decode("deadbeef");
 * }</pre>
 *
 * <p>Warning: BaseEncoding instances are immutable. Invoking a configuration method has no effect
 * on the receiving instance; you must store and use the new encoding instance it returns, instead.
 *
 * <pre>{@code
 * // Do NOT do this

Tout ceci est donc ce qui donne sa force à **FastAPI** (à travers Starlette) et lui permet d'avoir des performances aussi impressionnantes.
