<p>
        BOOST_FUSION_ADAPT_TPL_STRUCT is a macro that can be used to generate all

<p>
        The above macro generates the necessary code to adapt <code class="computeroutput"><span class="identifier">struct_name</span></code>
        or an arbitrary specialization of <code class="computeroutput"><span class="identifier">struct_name</span></code>
        as a model of <a class="link" href="../sequence/concepts/random_access_sequence.html" title="Random Access Sequence">Random
        Access Sequence</a>. The sequence <code class="computeroutput"><span class="special">(</span><span class="identifier">template_param0</span><span class="special">)(</span><span class="identifier">template_param1</span><span class="special">)...</span></code>
        declares the names of the template type parameters used. The sequence <code class="computeroutput"><span class="special">(</span><span class="identifier">specialization_param0</span><span class="special">)(</span><span class="identifier">specialization_param1</span><span class="special">)...</span></code> declares the template parameters of the
        actual specialization of <code class="computeroutput"><span class="identifier">struct_name</span></code>
        that is adapted as a fusion sequence. The sequence of <code class="computeroutput"><span class="special">(</span><span class="identifier">member_typeN</span><span class="special">,</span>
        <span class="identifier">member_nameN</span><span class="special">)</span></code>
        pairs declares the type and names of each of the struct members that are
        part of the sequence.
      </p>
<p>
        The macro should be used at global scope, and <code class="computeroutput"><span class="identifier">struct_name</span></code>
        should be the fully namespace qualified name of the struct to be adapted.
