std::contract_violation: std::contract_violation

NAME

std::contract_violation - std::contract_violation

Synopsis

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

                returns the line number where the contract violation happened
line_number (public member function)
                returns the name of the file where the contract violation happened
file_name (public member function)
                returns the name of the function where the contract violation happened
function_name (public member function)
                returns a string describing the predicate of the violated contract
comment (public member function)
                returns a string describing the assertion level of the violated contract
assertion_level (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.
