…This allows Adapt.adapt to be called with structs to change the underlieng data type. For example Adapt.adapt(CUArray, Split_matrix_A) adapts the split matrix to store the values on an equivalent CUDA storage format while maintaing the SplitMatrix wrapper. Not all structs of the PartititionedArrays module are implemented yet.

There was a problem hiding this comment.
I think we can just use Adapt.@adapt_structure T for these and the generic counterparts.
