    ```java
    Headers headers = Headers.of(name1, value1, name2, value2, ...).

 *  New: Make the content-type header optional for request bodies.
 *  New: `Response.isSuccessful()` is a convenient API to check response codes.
 *  New: The response body can now be read outside of the callback. Response

 * <p>The views returned by {@link #column}, {@link #columnKeySet()}, and {@link #columnMap()} have

 * Null row keys, columns keys, and values are not supported.
 *
 * <p>Lookups by row key are often faster than lookups by column key, because the data is stored in

Wenn Sie also Teil-Aktualisierungen empfangen wollen, die alle Attribute auslassen können, müssen Sie ein Modell haben, dessen Attribute alle als optional gekennzeichnet sind (mit Defaultwerten oder `None`).

Um zu unterscheiden zwischen Modellen für **Aktualisierungen**, mit lauter optionalen Werten, und solchen für die **Erzeugung**, mit benötigten Werten, können Sie die Techniken verwenden, die in [Extramodelle](extra-models.md) beschrieben wurden.

/// check | Inspired **FastAPI** to

Find ways to get great performance.

Along with Hug (as Hug is based on Falcon) inspired **FastAPI** to declare a `response` parameter in functions.

Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.
