<p>This error type is a light wrapper around <ahref="https://doc.rust-lang.org/stable/std/io/struct.Error.html"><code>std::io::Error</code></a>. In
particular, it adds the following information:</p>
<ul>
<li>The depth at which the error occurred in the file tree, relative to the
root.</li>
<li>The path, if any, associated with the IO error.</li>
<li>An indication that a loop occurred when following symbolic links. In this
case, there is no underlying IO error.</li>
</ul>
<p>To maintain good ergonomics, this type has a
<ahref="struct.Error.html#impl-From%3CError%3E"><code>impl From<Error> for std::io::Error</code></a> defined which preserves the original context.
This allows you to use an <ahref="https://doc.rust-lang.org/stable/std/io/type.Result.html"><code>io::Result</code></a> with methods in this crate if you don’t care about
accessing the underlying error data in a structured form.</p>
