| <p>See <a href="struct.FuturesOrdered.html"><code>FuturesOrdered</code></a> for a version of this |

| <p>This structure is optimized to manage a large number of futures. |
| Futures managed by <a href="struct.FuturesUnordered.html" title="FuturesUnordered"><code>FuturesUnordered</code></a> will only be polled when they |
| generate wake-up notifications. This reduces the required amount of work |
| needed to poll large numbers of futures.</p> |
| <p><a href="struct.FuturesUnordered.html" title="FuturesUnordered"><code>FuturesUnordered</code></a> can be filled by <a href="Iterator::collect"><code>collect</code></a>ing an |
| iterator of futures into a <a href="struct.FuturesUnordered.html" title="FuturesUnordered"><code>FuturesUnordered</code></a>, or by |
| <a href="struct.FuturesUnordered.html#method.push"><code>push</code></a>ing futures onto an existing |
| <a href="struct.FuturesUnordered.html" title="FuturesUnordered"><code>FuturesUnordered</code></a>. When new futures are added, |
| <a href="trait.Stream.html#tymethod.poll_next"><code>poll_next</code></a> must be called in order to begin receiving |
| wake-ups for new futures.</p> |
| <p>Note that you can create a ready-made <a href="struct.FuturesUnordered.html" title="FuturesUnordered"><code>FuturesUnordered</code></a> via the |
| <a href="Iterator::collect"><code>collect</code></a> method, or you can start with an empty set |
| with the <a href="struct.FuturesUnordered.html#method.new" title="FuturesUnordered::new"><code>FuturesUnordered::new</code></a> constructor.</p> |
| <p>This type is only available when the <code>std</code> or <code>alloc</code> feature of this |
| library is activated, and it is activated by default.</p> |
