Defined in header <contract> | ||

class contract_violation; | (since C++20) |
The class contract_violation describes information about a contract violation. It is generated by a C++ implementation and passed to a contract violation handler when a contract violation is detected.
Member functions
| line_number | returns the line number where the contract violation happened (public member function) |
| file_name | returns the name of the file where the contract violation happened (public member function) |
| function_name | returns the name of the function where the contract violation happened (public member function) |
| comment | returns a string describing the predicate of the violated contract (public member function) |
| assertion_level | returns a string describing the assertion level of the violated contract (public member function) |
std::contract_violation::line_number
std::uint_least32_t line_number() const noexcept; |
Returns the location of the source code where the contract violation happened. If the name is unknown, an implementation may return 0 instead.
std::contract_violation::file_name
std::string_view file_name() const noexcept; |
Returns the name of the the source file where the contract violation happened. If the name is unknown, an implementation may return an empty string_view instead.
std::contract_violation::function_name
std::string_view function_name() const noexcept; |
Returns the name of the function where the contract violation happened. If the name is unknown, an implementation may return an empty string_view instead.
std::contract_violation::comment
std::string_view comment() const noexcept; |
Returns an implementation-defined string describing the predicate of the violated contract.
std::contract_violation::assertion_level
std::string_view assertion_level() const noexcept; |
Returns a string describing the assertion level of the violated contract.
