| error[E0597]: `stmt` does not live long enough |

| LL | let stmt = Statement; |
| | ---- binding `stmt` declared here |
| LL | let rows = Rows(&stmt); |
| | ^^^^^ borrowed value does not live long enough |
| LL | rows.map(|row| row).next() |

| ... |
| LL | } |
| | - |
| | | |
| | `stmt` dropped here while still borrowed |
| | ... and the borrow might be used here, when that temporary is dropped and runs the destructor for type `Map<Rows<'_>, {closure@$DIR/issue-54556-stephaneyfx.rs:28:14: 28:19}>` |
| | |
| = note: the temporary is part of an expression at the end of a block; |
| consider forcing this temporary to be dropped sooner, before the block's local variables are dropped |
| help: for example, you could save the expression's value in a new local variable `x` and then make `x` be the expression at the end of the block |
| | |
| LL | let x = rows.map(|row| row).next(); x |
