BOOST_CONTRACT_AUDITS — Define this macro to evaluate and check audit assertions at run-time (undefined by default).
// In header: <boost/contract/core/config.hpp> BOOST_CONTRACT_AUDITS
Audit assertions and implementation checks programmed via
BOOST_CONTRACT_CHECK_AUDIT are always compiled and validated syntactically. However, they are not evaluated and checked at run-time unless this macro is defined (because these conditions can be computationally expensive, at least compared to the computational cost of executing the function body).
