|
Yeah ... also |
|
I am not exactly sure how to fix this, but I could take a closer look and try to make miri happy about it. In the meantime, feel free to push the fix to this branch or suggest anything :) |
|
These tests passed when running with Tree borrow even before the change is applied.I suspect an error is thrown previously due to some quirks of Stacked Borrow. I will annotate the result on the tests in this PR. |
|
Oh I see. That sounds tricky. |
|
Current status: I am trying to minimize the code that stacked borrow is complaining about and figure out what's going on underneath. But I might get to nowhere and ended up only annotating the test. This would for sure take some time and help is always welcomed. :) |
