error[E0382]: borrow of moved value: `s`
--> $DIR/issue-42796.rs:18:20
|
LL | let s = "Hello!".to_owned();
| - move occurs because `s` has type `String`, which does not implement the `Copy` trait
LL | let mut s_copy = s;
| - value moved here
...
LL | println!("{}", s);
| ^ value borrowed here after move
|
= note: this error originates in the macro `$crate::format_args_nl` which comes from the expansion of the macro `println` (in Nightly builds, run with -Z macro-backtrace for more info)
help: consider cloning the value if the performance cost is acceptable
|
LL | let mut s_copy = s.clone();
