<p>This module provides a nearly identical API via <ahref="struct.Regex.html"title="struct regex::bytes::Regex"><code>Regex</code></a> to the one found in
the top-level of this crate. There are two important differences:</p>
<ol>
<li>Matching is done on <code>&[u8]</code> instead of <code>&str</code>. Additionally, <code>Vec<u8></code>
is used where <code>String</code> would have been used in the top-level API.</li>
<li>Unicode support can be disabled even when disabling it would result in
