        <h3>Description</h3>
        <p><span>Objects of this type are used to interpret</span> <span>the query parameters as a bidirectional view</span>
<span>of key/value pairs.</span></p>

<p><span>The view does not retain ownership of the</span>
<span>elements and instead references the original</span>
<span>character buffer. The caller is responsible</span>
<span>for ensuring that the lifetime of the buffer</span>
<span>extends until it is no longer referenced.</span></p>

<h3>Example</h3>
<code>
url_view u( "?first=John&last=Doe" );

params_view p = u.params();
</code>
<p><span>Percent escapes in strings returned when</span>
<span>dereferencing iterators are automatically</span>
<span>decoded.</span></p>

<h3>Iterator Invalidation</h3>
<p><span>Changes to the underlying character buffer</span>
<span>can invalidate iterators which reference it.</span></p>
