|

|
|
--> $DIR/borrowck-escaping-closure-error-1.rs:23:11
|
||
|
|
|
|
||
|
|
23 | spawn(|| books.push(4));
|
||
|
|
| ^^ ----- `books` is borrowed here
|
||
|
|
| |
|
||
|
|
| may outlive borrowed value `books`
|
||
|
|
help: to force the closure to take ownership of `books` (and any other referenced variables), use the `move` keyword
|
||
|
|
|
|
||
|
|
23 | spawn(move || books.push(4));
|
||
|
|
| ^^^^^^^
