我不明白这个错误cannot move out of borrowed content.我收到了很多次,我总是解决它,但我从来没有理解为什么.

    println!("{}", line);

   |                                 ^^^^ cannot move out of borrowed content

我通过克隆解决了这个问题line:

error[E0507]: cannot move out of `*line` which is behind a shared reference
  --> src/main.rs:31:33
   |
31 |             for current_char in line.into_bytes().iter() {
   |                                 ^^^^ …
