regarded and expertly designed C++ library projects in the
world.

BOOST_CONTRACT_NO_ALL — Automatically defined by this library when contracts are not checked at all (neither for specifications nor for implementations).
// In header: <boost/contract/core/config.hpp>
BOOST_CONTRACT_NO_ALL
This macro is not a configuration macro and this library will generate a compile-time error if users try to define it directly. This library will automatically define this macro when users define all BOOST_CONTRACT_NO_INVARIANTS
, BOOST_CONTRACT_NO_PRECONDITIONS
, BOOST_CONTRACT_NO_POSTCONDITIONS
, BOOST_CONTRACT_NO_EXCEPTS
, and BOOST_CONTRACT_NO_CHECKS
. For example, users can manually program #ifndef
statements in their code using this macro to avoid including the boost/contract.hpp
header all together:
#include <boost/contract/core/config.hpp> #ifndef BOOST_CONTRACT_NO_ALL #include <boost/contract.hpp> #endif
Or, use the boost/contract_macro.hpp
header and related macros instead (because the boost/contract_macro.hpp
header is already optimized to not include other headers from this library when contracts are not checked, but recommended only for applications where it is truly necessary to completely remove contract code compilation from production code).
