error[E0521]: borrowed data escapes outside of function
|
|
--> $DIR/trait-objects.rs:15:5
|
|
|
|
|
LL | fn min_size(x: &mut dyn for<'a> StreamingIterator<Item<'a> = &'a i32>) -> usize {
|
|
| - - let's call the lifetime of this reference `'1`
|
|
| |
|
|
| `x` is a reference that is only valid in the function body
|
|
LL |
|
|
LL | x.size_hint().0
|
|
| ^^^^^^^^^^^^^
|
|
| |
|
|
| `x` escapes the function body here
|
|
| argument requires that `'1` must outlive `'static`
|
|
|
|
|
= note: due to current limitations in the borrow checker, this implies a `'static` lifetime
