error[E0597]: `stmt` does not live long enough
--> $DIR/issue-54556-stephaneyfx.rs:27:21
|
LL | let stmt = Statement;
| ---- binding `stmt` declared here
LL | let rows = Rows(&stmt);
| ^^^^^ borrowed value does not live long enough
LL | rows.map(|row| row).next()
| ------------------- a temporary with access to the borrow is created here ...
...
LL | }
| -
| |
| `stmt` dropped here while still borrowed
| ... and the borrow might be used here, when that temporary is dropped and runs the destructor for type `Map<Rows<'_>, {closure@$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
