which does not implement the `Copy` trait borrowed value does not live long enough //报错示例 fn get_str() -> &str { let s = String::from("hello"); &s } In this example, s is dropped at the end of get_str, so returning a reference to s would lead to a dangling reference....
v.iter()——对v执行deref(&v)得到&[T],然后*解引用得到[T];再调用切片类型的iter(&[T])方法,返回迭代器std::slice::Iter<'a, T>,其实现了Iteratortrait(关联类型为type Item = &'a T),因此v1_iter可以调用next()访问存储的数据(next()返回类型为Option<&'a T>),不可变借用; v.iter_mut()...
