          <h2>Flexible Responders</h2>
          <p>
            Handler functions in actix can return a wide range of objects that
            implement the <code>Responder</code> trait. This makes it a breeze
            to return consistent responses from your APIs.

          <h2>Powerful Extractors</h2>
          <p>
            Actix comes with a powerful extractor system that extracts data
            from the incoming HTTP request and passes it to your view functions.
            Not only does this make for a convenient API but it also means that
            your view functions can be synchronous code and still benefit
            from asynchronous IO handling.
          </p>

          <h2>Easy Form Handling</h2>
          <p>
            Handling multipart/urlencoded form data is easy. Just define
            a structure that can be deserialized and actix will handle
            the rest.

          <h2>Request Routing</h2>
          <p>
            An actix app comes with a URL routing system that lets you match on
            URLs and invoke individual handlers. For extra flexibility, scopes
            can be used.
