|
|
--> $DIR/borrowck-while-break.rs:7:20
|
|
|
|
|
LL | let v;
|
|
| - binding declared here but left uninitialized
|
|
LL | while cond {
|
|
| ---- if this condition isn't met and the `while` loop runs 0 times, `v` is not initialized
|
|
...
|
|
LL | println!("{}", v);
|
|
| ^ `v` used here but it is possibly-uninitialized
|

= 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)
