Struct GGLWEToGGSWKeyCompressed 

pub struct GGLWEToGGSWKeyCompressed<D: Data> { /* private fields */ }

Seed-compressed GGLWE-to-GGSW key-switching key layout.

A vector of GGLWECompressed entries, one per rank element, used for GGLWE-to-GGSW conversion. The mask of each GGLWE is regenerated from its PRNG seed during decompression.
