* Si estás comparando FastAPI, compáralo con un framework de aplicación web (o conjunto de herramientas) que proporcione validación de datos, serialización y documentación, como Flask-apispec, NestJS, Molten, etc. Frameworks con validación de datos, serialización y documentación automáticas integradas....

* `summary`: Um resumo curto da API.
* `description`: A descrição da sua API, que pode incluir markdown e será exibida na documentação.
* `routes`: Uma lista de rotas, que são cada uma das *operações de rota* registradas. Elas são obtidas de `app.routes`.

/// info | Informação

O parâmetro `summary` está disponível no OpenAPI 3.1.0 e superior, suportado pelo FastAPI 0.99.0 e superior.

   * If [routes] is non-null these are the resolved routes (ie. IP addresses) for the connection.
   * This is used to coalesce related domains to the same HTTP/2 connection, such as `square.com`
   * and `square.ca`.

### <a href="https://moltenframework.com/" class="external-link" target="_blank">Molten</a>

Molten мне попался на начальной стадии написания **FastAPI**. В нём были похожие идеи:

* Использование подсказок типов.
* Валидация и документация исходя из этих подсказок.
* Система внедрения зависимостей.

    val selection = routeSelector.next()
    dns.assertRequests(uriHost)
    val routes = selection.routes
    assertRoute(routes[0], address, Proxy.NO_PROXY, dns.lookup(uriHost, 0), uriPort)
    assertRoute(routes[1], address, Proxy.NO_PROXY, dns.lookup(uriHost, 1), uriPort)
    assertThat(selection.next()).isSameAs(routes[0])
    assertThat(selection.next()).isSameAs(routes[1])
    assertThat(selection.hasNext()).isFalse()

    planToReplace: ConnectPlan? = null,
    routes: List<Route>? = null,
  ): ReusePlan? {
    val result =
      connectionPool.callAcquirePooledConnection(
        doExtensiveHealthChecks = connectionUser.doExtensiveHealthChecks(),
        address = address,
        connectionUser = connectionUser,
        routes = routes,
        requireMultiplexed = planToReplace != null && planToReplace.isReady,

    * 따라서 FastAPI를 사용함으로써 개발 시간, 버그, 코드 라인을 줄일 수 있으며, FastAPI를 사용하지 않았을 때와 동일하거나 더 나은 성능을 얻을 수 있습니다(코드에서 모두 구현해야 하기 때문에).

* `summary`: A short summary of the API.
* `description`: The description of your API, this can include markdown and will be shown in the docs.
* `routes`: A list of routes, these are each of the registered *path operations*. They are taken from `app.routes`.

 * Since connections may be reused, the proxy selection, DNS, and connect events may not be present
 * for a call. In future releases of OkHttp these events may also occur concurrently to permit
 * multiple routes to be attempted simultaneously.
 *
 * Events and sequences of events may be repeated for retries and follow-ups.
 *
 * All event methods must execute fast, without external locking, cannot throw exceptions, attempt
