72 |     check_clean_tree(wt, &wt.basis_tree(), subpath).unwrap();
   |                          ^^^^^^^^^^^^^^^^ the trait `Tree` is not implemented for `Result<RevisionTree, breezyshim::error::Error>`
   |
   = help: the following other types implement trait `Tree`:
             AppliedPatches
             MemoryTree
             PreviewTree
             RevisionTree
             WorkingTree
   = note: required for the cast from `&Result<RevisionTree, breezyshim::error::Error>` to `&dyn Tree`
