+Subject: [PATCH] Increment `self.index` before calling |
220 |
+ `Iterator::self.a.__iterator_get_unchecked` in `Zip` `TrustedRandomAccess` |
221 |
+ specialization |
222 |
+ |
223 |
+Otherwise if `Iterator::self.a.__iterator_get_unchecked` panics the |
224 |
+index would not have been incremented yet and another call to |
225 |
+`Iterator::next` would read from the same index again, which is not |
226 |
+allowed according to the API contract of `TrustedRandomAccess` for |
227 |
+`!Clone`. |
