error[E0499]: cannot borrow `chars` as mutable more than once at a time
--> $DIR/issue-102972.rs:4:9
|
LL | for _c in chars.by_ref() {
| --------------
| |
| first mutable borrow occurs here
| first borrow later used here
LL | chars.next();
| ^^^^^^^^^^^^ second mutable borrow occurs here
|
= note: a for loop advances the iterator for you, the result is stored in `_c`.
= help: if you want to call `next` on a iterator within the loop, consider using `while let`.
error[E0382]: borrow of moved value: `iter`
--> $DIR/issue-102972.rs:12:9
|
LL | let mut iter = v.iter();
| -------- move occurs because `iter` has type `std::slice::Iter<'_, i32>`, which does not implement the `Copy` trait
LL | for _i in iter {
| ---- `iter` moved due to this implicit call to `.into_iter()`
LL | iter.next();
| ^^^^^^^^^^^ value borrowed here after move
|
= note: a for loop advances the iterator for you, the result is stored in `_i`.
= help: if you want to call `next` on a iterator within the loop, consider using `while let`.
note: `into_iter` takes ownership of the receiver `self`, which moves `iter`
