|

<p>The types in this module are to provide a lower-level API based around a
|
||
single connection. Accepting a connection and binding it with a service
|
||
are not handled at this level. This module provides the building blocks to
|
||
customize those things externally.</p>
|
||
<p>If you don’t have need to manage connections yourself, consider using the
|
||
higher-level <a href="../index.html" title="mod hyper::server">Server</a> API.</p>
