## Interface HttpResponse<T>

-     public interface HttpResponse<T>

  An HTTP response.

  The usual HTTP response attributes are available:

  - `statusCode()` the HTTP status code
  - `statusMessage()` the HTTP status message
  - `headers()` the HTTP headers
  - `version()` the HTTP version

  The body of the response is returned by `body()` decoded as the format specified by the `BodyCodec` that built the response.

  Keep in mind that using this `HttpResponse` impose to fully buffer the response body and should be used for payload that can fit in memory.
