Defined in header <contracts>
enum class detection_mode : /* unspecified */ {

predicate_false = 1 ,
evaluation_exception = 2

} ;
(since C++26)

The enumerators of std::contracts::detection_mode correspond to the reasons that cause the contract violation to happen under a context that is not manifestly constant-evaluated , with meanings listed below:

Enumerator Meaning
predicate_false the contract violation occurs because the result of the predicate is false
evaluation_exception the contract violation occurs because the evaluation of the predicate exits via an exception

Notes

If a contract violation occurs in a context that is manifestly constant-evaluated, the contract-violation handler is not invoked.
