## **FastAPI** utilitários { #fastapi-utilities }

**FastAPI** fornece várias ferramentas para cada um desses esquemas de segurança no módulo `fastapi.security` que simplificam o uso desses mecanismos de segurança.

Nos próximos capítulos você irá ver como adicionar segurança à sua API usando essas ferramentas disponibilizadas pelo **FastAPI**.

 *   <li>{@link Stopwatch}
 *   <li>{@link Throwables}
 *   <li>{@link Verify}
 * </ul>
 *
 * <h3>The rest</h3>
 *
 * This package also contains some classes with niche use cases (e.g., {@link Utf8} and {@link
 * Defaults}), as well as a number of classes that have been superseded by additions to the JDK.

 * Utility for traversing collections of classes and resources on the file system or inside JAR files.

 * Target directories on the file system or JAR files are provided as {@link URL}. The appropriate {@link Traverser} is returned depending on the protocol of the URL, and you can traverse classes and resources by calling its methods.

Et `Field` de Pydantic renvoie également une instance de `FieldInfo`.

`Body` renvoie aussi directement des objets d'une sous-classe de `FieldInfo`. Et il y en a d'autres que vous verrez plus tard qui sont des sous-classes de la classe `Body`.

* Documentação automática de modelos de dados com [**JSON Schema**](https://json-schema.org/) (já que o OpenAPI em si é baseado no JSON Schema).
* Projetado em torno desses padrões, após um estudo meticuloso. Em vez de uma camada improvisada por cima.
* Isso também permite o uso de **geração de código do cliente** automaticamente em muitas linguagens.
