error[E0382]: use of moved value: `a`
|
|
--> $DIR/option_mut.rs:6:20
|
|
|
|
|
LL | let a = Some(&mut ());
|
|
| - move occurs because `a` has type `Option<&mut ()>`, which does not implement the `Copy` trait
|
|
LL | let _ = method(a);
|
|
| - value moved here
|
|
LL | let _ = method(a);
|
|
| ^ value used here after move
|
|
|
|
|
note: consider changing this parameter type in function `method` to borrow instead if owning the value isn't necessary

|
--> $DIR/option_mut.rs:1:14

LL | fn method(a: Option<&mut ()>) {}

|
| ------ ^^^^^^^^^^^^^^^ this parameter takes ownership of the value
