Asegúrate de [Actualizar la versión de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} a al menos 0.95.1 antes de usar `Annotated`.

///

## Usar `Annotated` en el tipo del parámetro `q`

    public ResolutionNode resolveConflict(ResolutionNode node1, ResolutionNode node2) {
        try {
            ArtifactVersion version1 = node1.getArtifact().getSelectedVersion();
            ArtifactVersion version2 = node2.getArtifact().getSelectedVersion();

            return version1.compareTo(version2) > 0 ? node1 : node2;
        } catch (OverConstrainedVersionException exception) {
            // TODO log message or throw exception?

Pero antes de eso, manejar el código asíncrono era mucho más complejo y difícil.

En versiones previas de Python, podrías haber usado hilos o <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. Pero el código es mucho más complejo de entender, depurar y razonar.

    @Size(max = 1000)
    public String id;

    /**
     * The version number of the user for optimistic locking.
     * This field is required to prevent concurrent modification conflicts

* Si estás en una versión de Python inferior a 3.9, importa su versión equivalente del módulo `typing`
* Pasa el/los tipo(s) interno(s) como "parámetros de tipo" usando corchetes: `[` y `]`

En Python 3.9 sería:

```Python
my_list: list[str]
```

En versiones de Python anteriores a 3.9, sería:

```Python
from typing import List

my_list: List[str]

    DFS_WITNESS         // DFS namespace witness
}

public enum WitnessVersion {
    VERSION_1(0x00010001),  // Windows Server 2012
    VERSION_2(0x00020000);  // Windows Server 2012 R2+
    
    private final int version;
    
    WitnessVersion(int version) {
        this.version = version;
    }
    
    public int getValue() { return version; }
}
```
