|
||||
<p>Unlike other Rust programs, asynchronous applications require runtime
|
||||
support. In particular, the following runtime services are necessary:</p>
|
||||
<ul>
|
||||
<li>An <strong>I/O event loop</strong>, called the driver, which drives I/O resources and
|
||||
dispatches I/O events to tasks that depend on them.</li>
|
||||
<li>A <strong>scheduler</strong> to execute <a href="../../tokio/task/index.html">tasks</a> that use these I/O resources.</li>
|
||||
<li>A <strong>timer</strong> for scheduling work to run after a set period of time.</li>
|
||||
</ul>
|
||||
<p>Tokio's <a href="../../tokio/runtime/struct.Runtime.html"><code>Runtime</code></a> bundles all of these services as a single type, allowing
|
||||
them to be started, shut down, and configured together. However, often it is
|
||||
not required to configure a <a href="../../tokio/runtime/struct.Runtime.html"><code>Runtime</code></a> manually, and user may just use the
|
||||
<a href="../attr.main.html"><code>tokio::main</code></a> attribute macro, which creates a <a href="../../tokio/runtime/struct.Runtime.html"><code>Runtime</code></a> under the hood.</p>
|
||||
<h1 id="usage" class="section-header"><a href="#usage">Usage</a></h1>
|
||||
<p>When no fine tuning is required, the <a href="../attr.main.html"><code>tokio::main</code></a> attribute macro can be
|
||||
used.</p>

<h2 id="runtime-configurations" class="section-header"><a href="#runtime-configurations">Runtime Configurations</a></h2>
|
||||
<p>Tokio provides multiple task scheduling strategies, suitable for different
|
||||
applications. The <a href="../../tokio/runtime/struct.Builder.html">runtime builder</a> or <code>#[tokio::main]</code> attribute may be
|
||||
used to select which scheduler to use.</p>
|
||||
<h4 id="multi-thread-scheduler" class="section-header"><a href="#multi-thread-scheduler">Multi-Thread Scheduler</a></h4>
|
||||
<p>The multi-thread scheduler executes futures on a <em>thread pool</em>, using a
|
||||
work-stealing strategy. By default, it will start a worker thread for each
|
||||
CPU core available on the system. This tends to be the ideal configurations
|
||||
for most applications. The multi-thread scheduler requires the <code>rt-multi-thread</code>
|
||||
feature flag, and is selected by default:</p>
|
||||
|
||||
<div class="example-wrap"><pre class="rust rust-example-rendered">
|
||||
<span class="kw">use</span> <span class="ident">tokio</span>::<span class="ident">runtime</span>;
|
||||
|
||||
<span class="kw">let</span> <span class="ident">threaded_rt</span> <span class="op">=</span> <span class="ident">runtime</span>::<span class="ident">Runtime</span>::<span class="ident">new</span>()<span class="question-mark">?</span>;</pre></div>
|
||||
<p>Most applications should use the multi-thread scheduler, except in some
|
||||
niche use-cases, such as when running only a single thread is required.</p>
|
||||
<h4 id="current-thread-scheduler" class="section-header"><a href="#current-thread-scheduler">Current-Thread Scheduler</a></h4>
|
||||
<p>The current-thread scheduler provides a <em>single-threaded</em> future executor.
|
||||
All tasks will be created and executed on the current thread. This requires
|
||||
the <code>rt</code> feature flag.</p>
|
||||
|
||||
<div class="example-wrap"><pre class="rust rust-example-rendered">
|
||||
<span class="kw">use</span> <span class="ident">tokio</span>::<span class="ident">runtime</span>;

|
||||
<h4 id="resource-drivers" class="section-header"><a href="#resource-drivers">Resource drivers</a></h4>
|
||||
<p>When configuring a runtime by hand, no resource drivers are enabled by
|
||||
default. In this case, attempting to use networking types or time types will
|
||||
fail. In order to enable these types, the resource drivers must be enabled.
|
||||
This is done with <a href="../../tokio/runtime/struct.Builder.html#method.enable_io"><code>Builder::enable_io</code></a> and <a href="../../tokio/runtime/struct.Builder.html#method.enable_time"><code>Builder::enable_time</code></a>. As a
|
||||
shorthand, <a href="../../tokio/runtime/struct.Builder.html#method.enable_all"><code>Builder::enable_all</code></a> enables both resource drivers.</p>
|
||||
<h2 id="lifetime-of-spawned-threads" class="section-header"><a href="#lifetime-of-spawned-threads">Lifetime of spawned threads</a></h2>
|
||||
<p>The runtime may spawn threads depending on its configuration and usage. The
|
||||
multi-thread scheduler spawns threads to schedule tasks and for <code>spawn_blocking</code>
|
||||
calls.</p>
|
||||
<p>While the <code>Runtime</code> is active, threads may shutdown after periods of being
|
||||
idle. Once <code>Runtime</code> is dropped, all runtime threads are forcibly shutdown.
|
||||
Any tasks that have not yet completed will be dropped.</p>

<p>The runtime provides an I/O driver, task scheduler, <a href="../../tokio/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="../../tokio/runtime/struct.Runtime.html#method.new"><code>new</code></a>, or <a href="../../tokio/runtime/struct.Builder.html"><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>

<h1 id="shutdown" class="section-header"><a href="#shutdown">Shutdown</a></h1>
|

<p>Shutting down the runtime is done by dropping the value. The current
|

thread will block until the shut down operation has completed.</p>

<ul>
|

<li>Drain any scheduled work queues.</li>
|

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

<li>Drop the reactor.</li>
|

</ul>
|

<p>Once the reactor has dropped, any outstanding I/O resources bound to

that reactor will no longer function. Calling any method on them will
|

result in an error.</p>

<h1 id="sharing" class="section-header"><a href="#sharing">Sharing</a></h1>
|

<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
|
||||
accross 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>

<p>This can be useful if you want to drop a runtime from within another runtime.

Normally, dropping a runtime will block indefinitely for spawned blocking tasks

to complete, which would normally not be permitted within an asynchronous context.

By calling <code>shutdown_background()</code>, you can drop the runtime from such a context.</p>

may result in a resource leak (in that any blocking tasks are still running until they
