如何在基板的運行時獲取驗證器 vec

Question

我面臨着在運行時獲取驗證器的問題，基本上想將費用分配給驗證器。 但在驗證器獲取時出錯。

   pub struct DealWithFees<R>(sp_std::marker::PhantomData<R>);
impl<R> OnUnbalanced<NegativeImbalance<R>> for DealWithFees<R>
where
    R: pallet_balances::Config + pallet_authorship::Config,
{
    fn on_unbalanceds<B>(mut fees_then_tips: impl Iterator<Item = NegativeImbalance<R>>) {
        if let Some(fees) = fees_then_tips.next() {
            // for fees, 80% to treasury, 20% to author
            let mut split = fees.ration(80, 20);
            if let Some(tips) = fees_then_tips.next() {
                // for tips, if any, 100% to author
                tips.merge_into(&mut split.1);
            }
            // <Treasury<R> as OnUnbalanced<_>>::on_unbalanced(split.0);
            <ToAuthor<R> as OnUnbalanced<_>>::on_unbalanced(split.1);

            let mut validators = session::Module::<T>::validators();
        }
    }
}

您是否嘗試過編譯器錯誤給出的建議？ 嘗試將您的 T 泛型更改為 B？
