error[E0505]: cannot move out of `s` because it is borrowed
--> $DIR/btreemap_dropck.rs:15:10

LL | let s = String::from("Hello World!");

LL | let _map = BTreeMap::from_iter([((), PrintOnDrop(&s))]);
| -- borrow of `s` occurs here
LL | drop(s);
| ^ move out of `s` occurs here
LL | }
| - borrow might be used here, when `_map` is dropped and runs the `Drop` code for type `BTreeMap`

help: consider cloning the value if the performance cost is acceptable

LL | let _map = BTreeMap::from_iter([((), PrintOnDrop(&s.clone()))]);
