pub type SsaPolyIndexPrefixSize = Sum<U<SSA_INDEX_SIZE>, U<POLY_INDEX_SIZE>>;Expand description
Size of the SsaIndex and PolynomialIndex prefix prepended to the encrypted share.
Derived at compile time from size_of::<SsaIndex>() + size_of::<PolynomialIndex>() via
typenum’s Const/ToUInt machinery. The matching runtime invariant is asserted by
the size_of_indices_must_match unit test below.
