Rust 泛型函数接受原始整数和地毯整数

问：

我正在尝试编写一个对整数进行操作的泛型函数，它可以接受原始整数或多精度整数（通过）。棘手的一点是，对 rug s 的引用具有惰性算术运算，在转换为整数之前返回不完整的类型。所以我认为像下面这样的东西会起作用，但我似乎无法获得正确的生存期设置（并且 rust-analyzer 在提供帮助方面并不是非常冗长）：rugInteger

use rug::Integer;
use std::ops::Mul;

fn mymul<T, S>(x: &T, y: &T) -> T
where
    T: 'static + From<S>,
    for<'a> &'a T: Mul<&'a T, Output = S>,
{
    T::from(x * y)
}

fn main() {
    let x: u64 = 3847381;
    let y: u64 = 28478195;
    let rug_x = Integer::from(x);
    let rug_y = Integer::from(y);
    println!("{} == {:?}", mymul(&x, &y), mymul(&rug_x, &rug_y));
}

有错误

error[E0308]: mismatched types
  --> src/main.rs:22:43

22 |     println!("{} == {:?}", mymul(&x, &y), mymul(&rug_x, &rug_y));

知道如何正确地做这种事情吗？
