In order to assign a string to `b`, you have to move it or copy it from where it was. You can't move it out of `a`, because that would be unsafe -- the string owned by `b` would then be pointing to somewhere inside `a`. So, your only option is to copy it out. Because `String` is non-`Copy`, you would have to clone it:

```rust
b = a[index as usize].clone();

```

By the way, a more idiomatic way to write that loop would be

```rust
for b in a {
    // do whatever with b
}

```

Or, if you still want access to the index,

```rust
for i in 0..a.len() {
    b = a[i].clone();
}

```
