IDE 是 Visual Studio Code。这是我打开调试器时的日志：

2021-09-07 …mut鉴于向量在初始化后将不可变，在没有关键字的情况下初始化向量的好方法是什么？
例如：
// nums is a `i32` vector(Vec<i32>)
// here is to pad two 1s with both ends
let mut padded: Vec<i32> = vec![0; len_p];
padded[0] = 1;
padded[len_n + 1] = 1;
for (idx, &num) in nums.iter().enumerate(){
padded[idx + 1] = num;
}
// `padded` will be read-only/immutable ever since
否则，标记padded mut，简单地初始化它，在我看来是对不变性的浪费，因为我无法在初始化后强制执行它。
