<p>Migrating a project from RTIC <code>v1.0.x</code> to <code>v2.0.0</code> involves the following steps:</p>
<ol>
<li><code>v2.1.0</code> works on Rust Stable from 1.75 (<strong>recommended</strong>), while older versions require a <code>nightly</code> compiler via the use of <a href="https://github.com/rust-lang/rust/issues/63063"><code>#![type_alias_impl_trait]</code></a>.</li>
<li>Migrating from the monotonics included in <code>v1.0.x</code> to <code>rtic-time</code> and <code>rtic-monotonics</code>, replacing <code>spawn_after</code>, <code>spawn_at</code>.</li>
<li>Software tasks are now required to be <code>async</code>, and using them correctly.</li>
<li>Understanding and using data types provided by <code>rtic-sync</code>.</li>
</ol>
<p>For a detailed description of the changes, refer to the subchapters.</p>
<p>If you wish to see a code example of changes required, you can check out <a href="./migration_v1_v2/complete_example.html">the full example migration page</a>.</p>
<h4 id="tldr-too-long-didnt-read"><a class="header" href="#tldr-too-long-didnt-read">TL;DR (Too Long; Didn't Read)</a></h4>
<ol>
<li>Instead of <code>spawn_after</code> and <code>spawn_at</code>, you now use the <code>async</code> functions <code>delay</code>, <code>delay_until</code> (and related) with impls provided by <code>rtic-monotonics</code>.</li>
<li>Software tasks <em>must</em> be <code>async fn</code>s now. Not returning from a task is allowed so long as there is an <code>await</code> in the task. You can still <code>lock</code> shared resources.</li>
<li>Use <code>rtic_sync::arbiter::Arbiter</code> to <code>await</code> access to a shared resource, and <code>rtic_sync::channel::Channel</code> to communicate between tasks instead of <code>spawn</code>-ing new ones.</li>
</ol>
