response</p>
<p>An HTTP response consists of a head and a potentially optional body. The body
component is generic, enabling arbitrary types to represent the HTTP body.
For example, the body could be <code>Vec&lt;u8&gt;</code>, a <code>Stream</code> of byte chunks, or a
value that has been deserialized.</p>
<p>Typically you’ll work with responses on the client side as the result of
sending a <code>Request</code> and on the server you’ll be generating a <code>Response</code> to
send back to the client.</p>
<h2 id="examples"><a href="#examples">Examples</a></h2>
<p>Creating a <code>Response</code> to return</p>
