|
||
whether two file paths refer to the same file or directory.</p>
|
||
<p>Most uses of this crate should be limited to the top-level <a href="fn.is_same_file.html"><code>is_same_file</code></a>
|
||
function, which takes two file paths and returns true if they refer to the
|
||
same file or directory:</p>
|
||
|
||
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>same_file::is_same_file;
|
||
|
||
<span class="macro">assert!</span>(is_same_file(<span class="string">"/bin/sh"</span>, <span class="string">"/usr/bin/sh"</span>)<span class="question-mark">?</span>);</code></pre></div>
|
||
<p>Additionally, this crate provides a <a href="struct.Handle.html"><code>Handle</code></a> type that permits a more efficient
|
||
equality check depending on your access pattern. For example, if one wanted to
|
||
check whether any path in a list of paths corresponded to the process’ stdout
|
||
handle, then one could build a handle once for stdout. The equality check for
|
||
each file in the list then only requires one stat call instead of two. The code
|
||
might look like this:</p>
|
||
|
||
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>same_file::Handle;
|
||
|
||
<span class="kw">let </span>candidates = <span class="kw-2">&</span>[
|
||
<span class="string">"examples/is_same_file.rs"</span>,
|
||
<span class="string">"examples/is_stderr.rs"</span>,
|
||
<span class="string">"examples/stderr"</span>,
|
||
];
|
||
<span class="kw">let </span>stdout_handle = Handle::stdout()<span class="question-mark">?</span>;
|
||
<span class="kw">for </span>candidate <span class="kw">in </span>candidates {
|
||
<span class="kw">let </span>handle = Handle::from_path(candidate)<span class="question-mark">?</span>;
|
||
<span class="kw">if </span>stdout_handle == handle {
|
||
<span class="macro">println!</span>(<span class="string">"{:?} is stdout!"</span>, candidate);
|
||
} <span class="kw">else </span>{
|
||
<span class="macro">println!</span>(<span class="string">"{:?} is NOT stdout!"</span>, candidate);
|
||
}
|
||
}</code></pre></div>
