error[E0505]: cannot move out of `value` because it is borrowed
--> $DIR/if-let-guards-errors.rs:16:13
|
LL | let f = |x: &E| {
| ------- borrow of `value` occurs here
LL | match &x {
LL | E::Number(_) if let E::Number(ref mut n) = *value => { }
| ------ borrow occurs due to use in closure
...
LL | let x = value;
| ^^^^^ move out of `value` occurs here
LL |
LL | drop(f);
| - borrow later used here
error[E0382]: use of moved value: `value`
--> $DIR/if-let-guards-errors.rs:28:13
|
LL | fn if_let_move(value: Box<E>) {
| ----- move occurs because `value` has type `Box<E>`, which does not implement the `Copy` trait
LL | let f = |x: &E| {
| ------- value moved into closure here
LL | match &x {
LL | E::Number(_) if let E::String(s) = *value => { }
| ------ variable moved due to use in closure
...
LL | let x = value;
| ^^^^^ value used here after move

note: if `E` implemented `Clone`, you could clone the value
--> $DIR/if-let-guards-errors.rs:32:1

LL | E::Number(_) if let E::String(s) = *value => { }
| ------ you could clone this value
...
LL | enum E {
| ^^^^^^ consider implementing `Clone` for this type
error: aborting due to 2 previous errors
