error[E0382]: borrow of moved value: `x`

|
LL | let x = String::new();

= 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
