| <p>There are two levels of APIs provided for construct HTTP clients:</p> |
| <ul> |
| <li>The higher-level <a href="struct.Client.html"><code>Client</code></a> type.</li> |
| <li>The lower-level <a href="conn/index.html"><code>conn</code></a> module.</li> |
| </ul> |
| <h2 id="client"><a href="#client">Client</a></h2> |
| <p>The <a href="struct.Client.html"><code>Client</code></a> is the main way to send HTTP requests to a server. |
| The default <code>Client</code> provides these things on top of the lower-level API:</p> |
| <ul> |
| <li>A default <strong>connector</strong>, able to resolve hostnames and connect to |
| destinations over plain-text TCP.</li> |
| <li>A <strong>pool</strong> of existing connections, allowing better performance when |
| making multiple requests to the same hostname.</li> |
| <li>Automatic setting of the <code>Host</code> header, based on the request <code>Uri</code>.</li> |
| <li>Automatic request <strong>retries</strong> when a pooled connection is closed by the |
| server before any bytes have been written.</li> |
| </ul> |
| <p>Many of these features can configured, by making use of |
| <a href="struct.Client.html#method.builder"><code>Client::builder</code></a>.</p> |
| <h3 id="example"><a href="#example">Example</a></h3> |
| <p>For a small example program simply fetching a URL, take a look at the |
| <a href="https://github.com/hyperium/hyper/blob/master/examples/client.rs">full client example</a>.</p> |
