<p>We try to avoid links that easily become fragile. </p>
<p><strong>Do:</strong></p>
<ul>
<li>Link to <code>docs.rs</code> types to document the public API, but modify the link to use <code>latest</code> as the version.</li>
<li>Link to modules in the source code.</li>
<li>Create <a href="https://rust-lang.github.io/mdBook/format/mdbook.html?highlight=ANCHOR#including-portions-of-a-file">&quot;named anchors&quot;</a> and embed source code directly.</li>
</ul>
<p><strong>Don't:</strong></p>
<ul>
<li>Link to direct lines on github, even within a specific commit, unless you are trying to reference a historical piece of code (&quot;how things were at the time&quot;).</li>
