error[E0597]: `a` does not live long enough
--> $DIR/borrowing.rs:9:33
|
LL | Pin::new(&mut || yield &a).resume()
| ----------^
| | |
| | borrowed value does not live long enough
| value captured here by generator
| a temporary with access to the borrow is created here ...
LL |
LL | };
| -- ... and the borrow might be used here, when that temporary is dropped and runs the destructor for generator

| `a` dropped here while still borrowed
|
= 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. 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.
