如何在Rust中实现泛型添加

// 定义一个trait，名为Add
trait Add<RHS> {
    type Output;
    
    fn add(self, rhs: RHS) -> Self::Output;
}

// 实现Add trait的具体类型
impl Add<i32> for i32 {
    type Output = i32;
    
    fn add(self, rhs: i32) -> i32 {
        self + rhs
    }
}

impl Add<f64> for f64 {
    type Output = f64;
    
    fn add(self, rhs: f64) -> f64 {
        self + rhs
    }
}

fn main() {
    let a = 5;
    let b = 10;
    let c = 3.14;
    let d = 2.71;

    // 调用Add trait中的add方法
    let sum1 = a.add(b);
    let sum2 = c.add(d);

    println!("Sum1: {}", sum1);
    println!("Sum2: {}", sum2);
}
