}

A trait for engines keyswitching (discarding) LWE ciphertext vectors.

Semantics

This discarding operation fills the output LWE ciphertext vector with the element-wise keyswitch of the input LWE ciphertext vector, under the ksk lwe keyswitch key.

Required Methods

fn discard_keyswitch_lwe_ciphertext_vector( &mut self, output: &mut OutputCiphertextVector, input: &InputCiphertextVector, ksk: &KeyswitchKey, ) -> Result<(), LweCiphertextVectorDiscardingKeyswitchError<Self::EngineError>>

Keyswitch an LWE ciphertext vector.

unsafe fn discard_keyswitch_lwe_ciphertext_vector_unchecked( &mut self, output: &mut OutputCiphertextVector, input: &InputCiphertextVector, ksk: &KeyswitchKey, )

Unsafely keyswitch an LWE ciphertext vector.

Safety

For the general safety concerns regarding this operation, refer to the different variants of LweCiphertextVectorDiscardingKeyswitchError. For safety concerns specific to an engine, refer to the implementer safety section.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
