| operator bool () const noexcept

| operator int () const noexcept=delete
| Values of type bool participate in integral promotions. A prvalue of type bool can be converted to a prvalue of type int, with false becoming zero and true becoming one. This overload prevents the bool() operator above from participating in dangerous implicit conversion chains such as bool->int, bool->int->float, bool->int->double.
const char * | what () const noexcept
| Gets a textual description of the result. More...
