<p>This function is used to bootstrap the execution of a Tokio application. It
does the following:</p>
<ul>
<li>Start the Tokio runtime using a default configuration.</li>
<li>Spawn the given future onto the thread pool.</li>
<li>Block the current thread until the runtime shuts down.</li>
</ul>
<p>Note that the function will not return immediately once <code>future</code> has
completed. Instead it waits for the entire runtime to become idle.</p>
<p>See the <a href="../index.html">module level</a> documentation for more details.</p>

<h2>Search Tricks</h2>
<p>
Prefix searches with a type followed by a colon (e.g.
<code>fn:</code>) to restrict the search to a given type.
</p>
<p>
Accepted types are: <code>fn</code>, <code>mod</code>,
<code>struct</code>, <code>enum</code>,
<code>trait</code>, <code>type</code>, <code>macro</code>,
and <code>const</code>.
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code> or <code>* -> vec</code>)
