same for 2.072.0

problem are these constructors

    nothrow this(const(char)* topic, int partition)
    {
        topic_ = topic;
        partition_ = partition;
        offset_ = Offset.invalid;
        err_ = ErrorCode.no_error;
    }

    /// ditto
    this(const(char)* topic, int partition)
    {
        topic_ = topic;
        partition_ = partition;
        offset_ = Offset.invalid;
        err_ = ErrorCode.no_error;
    }

why is the no-throw even needed, the whole section is @nothrow?
