    BlockTensorView<Tensor> && DiagonalMdspecLike<tensor_mdspec_t<block_tensor_const_block_t<Tensor>>>

Detailed Description

BlockTensorView whose stored numerical blocks are generalized diagonals.

This refinement describes the representation of every stored block, independently of the sparse logical key pattern.
