automatically deleted.</p>
|
||
<p>This crate provides two temporary file variants: <code>TempFile</code> and <code>NamedTempFile</code>. When choosing
|
||
between the variants, prefer <code>TempFile</code> unless you either need to know the file's path or to be
|
||
able to persist it.</p>

|
||
<p><code>TempFile</code> will (almost) never fail to cleanup temporary files but <code>NamedTempFile</code> will if its
|
||
destructor doesn't run. This is because <code>TempFile</code> relies on the OS to cleanup the underlying
|
||
file so the file while <code>NamedTempFile</code> relies on its destructor to do so.</p>

||
<h2 id="security" class="section-header"><a href="#security">Security</a></h2>
|
||
<p>In the presence of pathological temporary file cleaner, relying on file paths is unsafe because
|
||
a temporary file cleaner could delete the temporary file which an attacker could then replace.</p>
|
||
<p><code>TempFile</code> doesn't rely on file paths so this isn't an issue. However, <code>NamedTempFile</code> does
|
||
rely on file paths.</p>

<h2>Search Tricks</h2>
|
||
|
||
<p>
|
||
Prefix searches with a type followed by a colon (e.g.
|
||
<code>fn:</code>) to restrict the search to a given type.
|
||
</p>
|
||
|
||
<p>
|
||
Accepted types are: <code>fn</code>, <code>mod</code>,
|
||
<code>struct</code>, <code>enum</code>,
|
||
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
||
and <code>const</code>.
|
||
</p>
|
||
|
||
<p>
|
||
Search functions by type signature (e.g.
|
||
<code>vec -> usize</code> or <code>* -> vec</code>)
