`Security` es en realidad una subclase de `Depends`, y tiene solo un parámetro extra que veremos más adelante.

Pero al usar `Security` en lugar de `Depends`, **FastAPI** sabrá que puede declarar scopes de seguridad, usarlos internamente y documentar la API con OpenAPI.

Pero cuando importas `Query`, `Path`, `Depends`, `Security` y otros de `fastapi`, en realidad son funciones que devuelven clases especiales.

* **Convertir datos**: de la request al tipo requerido.
* **Validar datos**: provenientes de cada request:
    * Generando **errores automáticos** devueltos al cliente cuando los datos son inválidos.
* **Documentar** la API usando OpenAPI:
    * Que luego es usada por las interfaces de documentación interactiva automática.

Luego dirígete a la interfaz de `/docs`, verás que **FastAPI** está usando estos **modelos** para **documentar** la API, y los usará para **serializar** y **validar** los datos también.

# Multi-Channel Feature - Detailed Design Document

## 1. Overview

SMB3 Multi-Channel enables the use of multiple network connections between client and server, providing increased throughput, network fault tolerance, and automatic failover capabilities. This feature aggregates bandwidth across multiple NICs and provides seamless failover when network paths fail.

## 2. Protocol Specification Reference

    /*
     * GWT claims to support java.lang.Character's char-classification methods, but it actually only
     * works for ASCII. So for now, assume any non-ASCII characters are valid. The only place this
     * seems to be documented is here:
     * https://groups.google.com/d/topic/google-web-toolkit-contributors/1UEzsryq1XI
     *
     * <p>ASCII characters in the part are expected to be valid per RFC 1035, with underscore also

# Witness Protocol Feature - Detailed Design Document

## 1. Overview

The SMB Witness Protocol enables rapid notification of resource changes in a clustered file server environment. It provides fast failover capabilities by allowing clients to register for notifications about server node availability, share movement, and other critical cluster events.

## 2. Protocol Specification Reference

    * Verifica que tem an atributo opcional `is_offer`, que deve ser `bool`, se presente.
    * Tudo isso também funciona para objetos JSON profundamente aninhados.
* Converter de e para JSON automaticamente.
* Documentar tudo com OpenAPI, que poderá ser usado por:
    * Sistemas de documentação interativos.
    * Sistemas de clientes de geração de código automáticos, para muitas linguagens.
