Rust学习——简单链表的实现

1
struct Node<T>{
2
    data:T,
3
    next:Option<Box<Node<T>>>
4
}

1
type Link<T> = Option<Box<Node<T>>>
2
pub struct SimpleLinkedList<T>{
3
    head: Link<T>
4
    len: usize
5
}

1
impl<T> SimpleLinkedList<T>{
2
    pub fn new()-> self {
3
        Self{head:None,len:0}
4
    }
5
}
