    Constructs new error code.

    1) Constructs error code with default value. Equivalent to error_code(0, std::system_category()).
    2) Constructs error code with ec as the platform-dependent error code and ecat as the corresponding error category.
    3) Constructs error code from an error code enum e. Equivalent to *this = std::make_error_code(e). The overload participates in overload resolutions only if std::is_error_code_enum<ErrorCodeEnum>::value == true.
