BOOST_CONTRACT_NO_ENTRY_INVARIANTS — If defined, this library does not check class invariants at entry (undefined by default).
// In header: <boost/contract/core/config.hpp> BOOST_CONTRACT_NO_ENTRY_INVARIANTS
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 at entry. In addition, users can manually program
#ifndef statements in their code using this macro to completely disable compilation of entry class invariants or use the macros defined in
boost/contract_macro.hpp (recommended only for applications where it is truly necessary to completely remove contract code compilation from production code).
This macro is automatically defined when
BOOST_CONTRACT_NO_INVARIANTS is defined.
