error[E0507]: cannot move out of `x`, a captured variable in an `Fn` closure
--> $DIR/borrowck-in-static.rs:5:17
|
LL | let x = Box::new(0);
| - ----------- move occurs because `x` has type `Box<i32>`, which does not implement the `Copy` trait
| |
| captured outer variable
LL | Box::new(|| x)
| -- ^ `x` is moved here
| |
| captured by this `Fn` closure
|
= help: `Fn` and `FnMut` closures require captured values to be able to be consumed multiple times, but `FnOnce` closures may consume them only once
help: consider cloning the value if the performance cost is acceptable
|
LL | Box::new(|| x.clone())
