2020-09-25：rust中Point是结构体类型，【let p1=Point{x:25,y:25}；let p2=p1；】...

struct Point {
    x: i64,
    y: i64,
}

fn main() {
    let p1 = Point { x: 25, y: 25 };
    println!("p1.x address: {:p}", &(p1.x));
    println!("p1 address: {:p}", &p1);
    println!("p1.x和p1的地址相同，说明p1存的是内容，而不是地址。");
    println!("------------");
    let p2 = p1;
    println!("p2.x address: {:p}", &(p2.x));
    println!("p2 address: {:p}", &p2);
    println!("p1.x和p2.x的地址不同，说明p1和p2的内存空间不一样，不是同一个对象。");
}
