Detailed Description

template<class LeafStorage = HostStorage>
struct uni20::PackedDiagonalBlockStorage< LeafStorage >

Sparse BlockTensor storage packing each generalized diagonal block into one leaf buffer.

Every explicitly stored logical block contains only the entries whose dense indices are all equal. Logical block presence remains controlled by the owning BlockTensor's stored-key set.

Template Parameters

LeafStorage

Immediate contiguous host storage for compressed values.
