使用 Substrate 的 decl_event 时，如何隐藏 Clippy 关于“不需要的单元表达式”的警告？

问题描述

拥有类似于 Substrate 框架的源代码：

private void InitializeComponent()
{
    var vm = new MainWindowviewmodel();

    for(int i = 0; i < 2; i++)
    {
        var panelVm = new TestPanelviewmodel();

        for(int j = 0; j < 10; j++)
        {
            panelVm.AllTests.Add(new TestItemviewmodel
            {
                TestName = $"Test{j}-{i}"
            });
        }
        vm.Panels.Add(panelVm);

    }
    AvaloniaXamlLoader.Load(this);

    this.DataContext = vm;
}

    pub enum Event<T>
    where
        AccountId = <T as frame_system::Config>::AccountId,ChipBalance = <T as Config>::ChipBalance,{
        /// Buy chips event
        BuyChips(AccountId,ChipBalance),/// Redemption amount with chips event
        Redemption(AccountId,/// Pledge chips
        Reserve(AccountId,/// Cancel pledge chips
        Unreserve(AccountId,/// Transfer the chips in the pledge to others
        RepatriateReserved(AccountId,AccountId,}
);

是否有更好的解决方案来隐藏为 Clippy lints 创建自定义规则的警告？

解决方法

我的猜测是由于 df = pd.DataFrame({'ID': [1,5,7,1,4,7],'Owns_car': [1,0],'owns_bike': [0,1]}) df.groupby('ID').max().reset_index() 实现中的单元。这可以解决它：

From<Event> for ()
