### オープンスタンダード準拠

* API作成のための<a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a>。これは、<abbr title="also known as: endpoints, routes">path</abbr> <abbr title="also known as HTTP methods, as POST, GET, PUT, DELETE">operations</abbr>の宣言、パラメータ、ボディリクエスト、セキュリティなどを含んでいます。

- One new field "InternalTrafficPolicy" in Service is added.
  It specifies if the cluster internal traffic should be routed to all endpoints or node-local endpoints only.
  "Cluster" routes internal traffic to a Service to all endpoints.
  "Local" routes traffic to node-local endpoints only, and traffic is dropped if no node-local endpoints are ready.

  // 	  :443 for https.
  // Both these may change in the future.
  // Incoming requests are matched against the host before the
  // IngressRuleValue. If the host is unspecified, the Ingress routes all
  // traffic based on the specified IngressRuleValue.
  //
  // host can be "precise" which is a domain name without the terminating dot of
  // a network host (e.g. "foo.bar.com") or "wildcard", which is a domain name

The dependency injection system requires pre-registration of the dependencies and the dependencies are solved based on the declared types. So, it's not possible to declare more than one "component" that provides a certain type.

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

Mais à un moment donné il n'y avait pas d'autre option que de créer quelque chose qui offrait toutes ces
fonctionnalités, en reprenant et en combinant de la meilleure façon possible les meilleures idées des outils

   * Evaluates whether the argument is a 6to4 address.
   *
   * <p>6to4 addresses begin with the {@code "2002::/16"} prefix. The next 32 bits are the IPv4
   * address of the host to which IPv6-in-IPv4 tunneled packets should be routed.
   *
   * <p>For more on 6to4 addresses see section 2 of <a target="_parent"
   * href="http://tools.ietf.org/html/rfc3056#section-2">RFC 3056</a>.
