error[E0309]: the parameter type `T` may not live long enough
--> $DIR/issue-84931.rs:14:21
|
LL | type Item<'a> = &'a mut T;
| -- ^^^^^^^^^ ...so that the reference type `&'a mut T` does not outlive the data it points at
| |
| the parameter type `T` must be valid for the lifetime `'a` as defined here...
|
help: consider adding an explicit lifetime bound
|
LL | type Item<'a> = &'a mut T where T: 'a;

error[E0477]: the type `StreamingSliceIter<'b, T>` does not fulfill the required lifetime
