<p>This function currently corresponds to the <code>mkdir</code> function on Unix
|
||
and the <code>CreateDirectory</code> function on Windows.
|
||
Note that, this <a href="https://doc.rust-lang.org/std/io/index.html#platform-specific-behavior">may change in the future</a>.</p>
|
||
<p><strong>NOTE</strong>: If a parent of the given path doesn’t exist, this function will
|
||
return an error. To create a directory and all its missing parents at the
|
||
same time, use the <a href="fn.create_dir_all.html" title="fn tokio::fs::create_dir_all"><code>create_dir_all</code></a> function.</p>
|
||
<h2 id="errors"><a class="doc-anchor" href="#errors">§</a>Errors</h2>
|
||
<p>This function will return an error in the following situations, but is not
|
||
limited to just these cases:</p>
|
||
<ul>
|
||
<li>User lacks permissions to create directory at <code>path</code>.</li>
|
||
<li>A parent of the given path doesn’t exist. (To create a directory and all
|
||
its missing parents at the same time, use the <a href="fn.create_dir_all.html" title="fn tokio::fs::create_dir_all"><code>create_dir_all</code></a>
|
||
function.)</li>
|
||
<li><code>path</code> already exists.</li>
