37<p>If this macro is defined, this library internal code is also optimized to reduce compile-time (not just run-time) overhead associated with checking class invariants. In addition, users can manually program <code class="computeroutput">#ifndef</code> statements in their code using this macro to completely disable compilation of class invariants or use the macros defined in <code class="computeroutput">boost/contract_macro.hpp</code> (recommended only for applications where it is truly necessary to completely remove contract code compilation from production code).</p>
38<p>Defining this macro is equivalent to defining both  <code class="computeroutput"><a class="link" href="BOOST_CO_idm46268585449728.html" title="Macro BOOST_CONTRACT_NO_ENTRY_INVARIANTS">BOOST_CONTRACT_NO_ENTRY_INVARIANTS</a></code> and  <code class="computeroutput"><a class="link" href="BOOST_CO_idm46268585442112.html" title="Macro BOOST_CONTRACT_NO_EXIT_INVARIANTS">BOOST_CONTRACT_NO_EXIT_INVARIANTS</a></code>.</p>
