<span class='doccomment'>/// A compiled regular expression</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// It is represented as either a sequence of bytecode instructions (dynamic)</span>
<span class='doccomment'>/// or as a specialized Rust function (native). It can be used to search, split</span>
<span class='doccomment'>/// or replace text. All searching is done with an implicit `.*?` at the</span>
<span class='doccomment'>/// beginning and end of an expression. To force an expression to match the</span>
<span class='doccomment'>/// whole string (or a prefix or a suffix), you must use an anchor like `^` or</span>
<span class='doccomment'>/// `$` (or `\A` and `\z`).</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// While this crate will handle Unicode strings (whether in the regular</span>
<span class='doccomment'>/// expression or in the search text), all positions returned are **byte</span>
<span class='doccomment'>/// indices**. Every byte index is guaranteed to be at a Unicode code point</span>
<span class='doccomment'>/// boundary.</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// The lifetimes `&#39;r` and `&#39;t` in this crate correspond to the lifetime of a</span>
<span class='doccomment'>/// compiled regular expression and text to search, respectively.</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// The only methods that allocate new strings are the string replacement</span>
<span class='doccomment'>/// methods. All other methods (searching and splitting) return borrowed</span>
<span class='doccomment'>/// pointers into the string given.</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// # Examples</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// Find the location of a US phone number:</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// ```rust</span>
<span class='doccomment'>/// # use regex::Regex;</span>
<span class='doccomment'>/// let re = Regex::new(&quot;[0-9]{3}-[0-9]{3}-[0-9]{4}&quot;).unwrap();</span>
<span class='doccomment'>/// assert_eq!(re.find(&quot;phone: 111-222-3333&quot;), Some((7, 19)));</span>
<span class='doccomment'>/// ```</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// # Using the `std::str::StrExt` methods with `Regex`</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// &gt; **Note**: This section requires that this crate is currently compiled with</span>
<span class='doccomment'>/// &gt;           the `pattern` Cargo feature enabled.</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// Since `Regex` implements `Pattern`, you can use regexes with methods</span>
<span class='doccomment'>/// defined on `std::str::StrExt`. For example, `is_match`, `find`, `find_iter`</span>
<span class='doccomment'>/// and `split` can be replaced with `StrExt::contains`, `StrExt::find`,</span>
<span class='doccomment'>/// `StrExt::match_indices` and `StrExt::split`.</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// Here are some examples:</span>
<span class='doccomment'>///</span>
<span class='doccomment'>/// ```rust,ignore</span>
<span class='doccomment'>/// # use regex::Regex;</span>
<span class='doccomment'>/// let re = Regex::new(r&quot;\d+&quot;).unwrap();</span>
<span class='doccomment'>/// let haystack = &quot;a111b222c&quot;;</span>

    <span class='doccomment'>///</span>
    <span class='doccomment'>/// ```rust</span>
    <span class='doccomment'>/// # extern crate regex; use regex::Regex;</span>

    <span class='doccomment'>/// # }</span>
    <span class='doccomment'>/// ```</span>
    <span class='doccomment'>///</span>
    <span class='doccomment'>/// Note that using `$2` instead of `$first` or `$1` instead of `$last`</span>

            <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>typedef</code> (or
                <code>tdef</code>).
            </p>
            <p>
                Search functions by type signature (e.g.
                <code>vec -> usize</code>)
