| <p>The runtime provides an I/O driver, task scheduler, <a href="../time/index.html">timer</a>, and |
| blocking pool, necessary for running asynchronous tasks.</p> |
| <p>Instances of <code>Runtime</code> can be created using <a href="method@Self::new"><code>new</code></a>, or <a href="struct@Builder"><code>Builder</code></a>. |
| However, most users will use the <code>#[tokio::main]</code> annotation on their |
| entry point instead.</p> |
| <p>See <a href="index.html">module level</a> documentation for more details.</p> |
| <h2 id="shutdown"><a href="#shutdown">Shutdown</a></h2> |
| <p>Shutting down the runtime is done by dropping the value, or calling |
| <a href="struct.Runtime.html#method.shutdown_background" title="Runtime::shutdown_background"><code>Runtime::shutdown_background</code></a> or <a href="struct.Runtime.html#method.shutdown_timeout" title="Runtime::shutdown_timeout"><code>Runtime::shutdown_timeout</code></a>.</p> |
| <p>Tasks spawned through <a href="struct.Runtime.html#method.spawn" title="Runtime::spawn"><code>Runtime::spawn</code></a> keep running until they yield. |
| Then they are dropped. They are not <em>guaranteed</em> to run to completion, but |
| <em>might</em> do so if they do not yield until completion.</p> |
| <p>Blocking functions spawned through <a href="struct.Runtime.html#method.spawn_blocking" title="Runtime::spawn_blocking"><code>Runtime::spawn_blocking</code></a> keep running |
| until they return.</p> |
| <p>The thread initiating the shutdown blocks until all spawned work has been |
| stopped. This can take an indefinite amount of time. The <code>Drop</code> |
| implementation waits forever for this.</p> |
| <p><code>shutdown_background</code> and <code>shutdown_timeout</code> can be used if waiting forever |
| is undesired. When the timeout is reached, spawned work that did not stop |
| in time and threads running it are leaked. The work continues to run until |
| one of the stopping conditions is fulfilled, but the thread initiating the |
| shutdown is unblocked.</p> |
| <p>Once the runtime has been dropped, any outstanding I/O resources bound to |
| it will no longer function. Calling any method on them will result in an |
| error.</p> |
| <h2 id="sharing"><a href="#sharing">Sharing</a></h2> |
| <p>The Tokio runtime implements <code>Sync</code> and <code>Send</code> to allow you to wrap it |
| in a <code>Arc</code>. Most fn take <code>&self</code> to allow you to call them concurrently |
| 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> |
