* An HTTP response.

* - {@link #statusCode()} the HTTP status code
* - {@link #statusMessage()} the HTTP status message
* - {@link #headers()} the HTTP headers
* - {@link #version()} the HTTP version
*
*
* The body of the response is returned by {@link #body()} decoded as the format specified by the {@link com.arangodb.shaded.vertx.ext.web.codec.BodyCodec} that
* built the response.
*
* Keep in mind that using this {@code HttpResponse} impose to fully buffer the response body and should be used for payload
* that can fit in memory.
