<p><code>actix-identity</code> can be used to track identity of a user across multiple requests. It is built

on top of HTTP sessions, via <a href="https://docs.rs/actix-session"><code>actix-session</code></a>.</p>

<p>By default, <code>actix-identity</code> does not automatically log out users. You can change this behaviour
|
||
by customising the configuration for <a href="struct.IdentityMiddleware.html" title="IdentityMiddleware"><code>IdentityMiddleware</code></a> via <a href="struct.IdentityMiddleware.html#method.builder" title="IdentityMiddleware::builder"><code>IdentityMiddleware::builder</code></a>.</p>
|

<p>In particular, you can automatically log out users who:</p>
|
||
<ul>
|
||
<li>have been inactive for a while (see <a href="config/struct.IdentityMiddlewareBuilder.html#method.visit_deadline"><code>IdentityMiddlewareBuilder::visit_deadline</code></a>;</li>

<li>logged in too long ago (see <a href="config/struct.IdentityMiddlewareBuilder.html#method.login_deadline"><code>IdentityMiddlewareBuilder::login_deadline</code></a>).</li>
