Il y a eu de nombreux outils créés auparavant qui ont contribué à inspirer sa création.

J'ai évité la création d'un nouveau framework pendant plusieurs années. J'ai d'abord essayé de résoudre toutes les fonctionnalités couvertes par **FastAPI** en utilisant de nombreux frameworks, plug-ins et outils différents.

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]
<span style="color: green;">INFO</span>:     Started server process [28722]
<span style="color: green;">INFO</span>:     Waiting for application startup.
<span style="color: green;">INFO</span>:     Application startup complete.
```

    }

    public void setStreet_Terms(ConditionOptionCall<TermsAggregationBuilder> opLambda) {
        setStreet_Terms("street", opLambda, null);
    }

    public void setStreet_Terms(ConditionOptionCall<TermsAggregationBuilder> opLambda, OperatorCall<BsUserCA> aggsLambda) {
        setStreet_Terms("street", opLambda, aggsLambda);
    }

### Ejecutar la App

Puedes ejecutar la aplicación:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

class EncodableTest {

    // Generates a few representative slices and destination indices.
    static Stream<Arguments> byteEncodableArgs() {
        return Stream.of(
                // srcLen, off, len, dstIndex
                Arguments.of(makeSeq(8), 0, 8, 0), // full copy at index 0
                Arguments.of(makeSeq(10), 2, 5, 3), // middle slice, non-zero dst index

```Python
say_hi(name=None)  # Das funktioniert, None is gültig 🎉
```

Die gute Nachricht ist, dass Sie sich darüber keine Sorgen mehr machen müssen, wenn Sie Python 3.10 verwenden, da Sie einfach `|` verwenden können, um Vereinigungen von Typen zu definieren:

`Field` funciona de la misma manera que `Query`, `Path` y `Body`, tiene todos los mismos parámetros, etc.

/// note | Detalles técnicos

En realidad, `Query`, `Path` y otros que verás a continuación crean objetos de subclases de una clase común `Param`, que es a su vez una subclase de la clase `FieldInfo` de Pydantic.

Y `Field` de Pydantic también regresa una instance de `FieldInfo`.
