def ut3_leaf_structure(d: int):  # leaf-structure template for stacking.apply_func_to_leaf_subtrees

Template marking one uniform-T3 .data leaf for the tree machinery in stacking.py.

The leaf is (tucker_supercore, tt_supercore, shape, (tucker_mask, tt_mask)). The shape int tuple has d int leaves, so the template must encode its length: a bare None there fails to match (an int tuple is a Sequence, unlike the ndarray leaves, so the walker would recurse into it).

Parameters:

d (int)
