|
||
<p>Creating a <code>AsyncResolver</code> returns a new handle and a future that should
|
||
be spawned on an executor to drive the background work. The lookup methods
|
||
on <code>AsyncResolver</code> request lookups from the background task.</p>
|
||
<p>The futures returned by a <code>AsyncResolver</code> and the corresponding background
|
||
task need not be spawned on the same executor, or be in the same thread.
|
||
Additionally, one background task may have any number of handles; calling
|
||
<code>clone()</code> on a handle will create a new handle linked to the same
|
||
background task.</p>
|
||
<p><em>NOTE</em> If lookup futures returned by a <code>AsyncResolver</code> and the background
|
||
future are spawned on two separate <code>CurrentThread</code> executors, one thread
|
||
cannot run both executors simultaneously, so the <code>run</code> or <code>block_on</code>
|
||
functions will cause the thread to deadlock. If both the background work
|
||
and the lookup futures are intended to be run on the same thread, they
|
||
should be spawned on the same executor.</p>
|
||
<p>The background task manages the name server pool and other state used
|
||
to drive lookups. When this future is spawned on an executor, it will
|
||
first construct and configure the necessary client state, before checking
|
||
for any incoming lookup requests, handling them, and and yielding. It will
|
||
continue to do so as long as there are still any [<code>AsyncResolver</code>] handle
|
||
linked to it. When all of its [<code>AsyncResolver</code>]s have been dropped, the
|
||
background future will finish.</p>
