}

A trait for engines packing keyswitching (discarding) LWE ciphertext vectors into a GLWE ciphertext.

Semantics

This discarding operation fills the output GLWE ciphertext with the packing keyswitch of the input LWE ciphertext vector, under the pksk packing keyswitch key.

Formal Definition

) -> Result<(), LweCiphertextVectorGlweCiphertextDiscardingPackingKeyswitchError<Self::EngineError>>

Packing keyswitch an LWE ciphertext vector.
