| However, most users will use the <code>#[tokio::main]</code> annotation on their |

| <li>Drop any futures that have not yet completed.</li> |
| <li>Drop the reactor.</li> |

| <p>The Tokio runtime implements <code>Sync</code> and <code>Send</code> to allow you to wrap it |

| across multiple threads.</p> |
| <p>Calls to <code>shutdown</code> and <code>shutdown_timeout</code> require exclusive ownership of |
| the runtime type and this can be achieved via <code>Arc::try_unwrap</code> when only |
| one strong count reference is left over.</p> |
