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 ...

|
|
| |
|
|
| `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
