<p>This type allows you to wait on a sequence of instants with a certain
|
||
|
|
duration between each instant. Unlike calling <a href="fn.sleep.html" title="fn actix_web::rt::time::sleep"><code>sleep</code></a> in a loop, this lets
|
||
|
|
you count the time spent between the calls to <a href="fn.sleep.html" title="fn actix_web::rt::time::sleep"><code>sleep</code></a> as well.</p>
|
||
|
|
<p>An <code>Interval</code> can be turned into a <code>Stream</code> with <a href="https://docs.rs/tokio-stream/latest/tokio_stream/wrappers/struct.IntervalStream.html"><code>IntervalStream</code></a>.</p>
