error_condition() noexcept;
Effects: Initializes val_ with 0 and cat_ with &generic_category().
error_condition(int val, const error_category& cat) noexcept;
Effects: Initializes val_ with val and cat_ with &cat.
template<class ErrorConditionEnum> error_condition(ErrorConditionEnum e) noexcept;
Constraints: is_error_condition_enum_v is true.
Effects: Equivalent to:error_condition ec = make_error_condition(e); assign(ec.value(), ec.category());
