Rust LinkedList第二个可变借入，同时将第一个项目移动到末尾

use std::collections::LinkedList;

fn main() {
    let mut list: LinkedList<i32> = LinkedList::new();
    list.push_back(1);
    list.push_back(2);
    list.push_back(3);
    
    let (mut first_part, mut second_part) = list.split_at_mut(2);
    
    // 对第二个节点进行可变借用
    let second_node = second_part.front_mut().unwrap();
    
    // 进行相关操作
    *second_node += 1;
    
    // 打印修改后的链表
    for item in first_part.iter().chain(second_part.iter()) {
        println!("{}", item);
    }
}

use std::collections::LinkedList;

fn main() {
    let mut list: LinkedList<i32> = LinkedList::new();
    list.push_back(1);
    list.push_back(2);
    list.push_back(3);
    
    if let Some(first_node) = list.pop_front() {
        list.push_back(first_node);
    }
    
    // 打印移动后的链表
    for item in list.iter() {
        println!("{}", item);
    }
}
