error_code() noexcept;
Effects: Initializes val_ with 0 and cat_ with &system_category().
error_code(int val, const error_category& cat) noexcept;
Effects: Initializes val_ with val and cat_ with &cat.
template<class ErrorCodeEnum> error_code(ErrorCodeEnum e) noexcept;
Constraints: is_error_code_enum_v is true.
Effects: Equivalent to:error_code ec = make_error_code(e); assign(ec.value(), ec.category());
