Struct GLWETensorKey 

pub struct GLWETensorKey<D: Data>(/* private fields */);

GLWE tensor key used for relinearisation after a tensor product.

Wraps a GGLWE whose rank_in equals the number of unique pairs max(1, rank*(rank+1)/2) produced by the tensor product.

D: Data is the backing storage type (e.g. Vec<u8>, &[u8], &mut [u8]).
