Struct CompressedKeySwitchingKey

pub struct CompressedKeySwitchingKey { /* private fields */ }

Available on crate feature shortint only.

A structure containing the casting public key.

The casting key is generated by the client and is meant to be published: the client sends it to the server so it can cast from one set of parameters to another.

Implementations

impl CompressedKeySwitchingKey

pub fn new<'input_key, InputEncryptionKey>( input_key_pair: (InputEncryptionKey, Option<&CompressedServerKey>), output_key_pair: (&ClientKey, &CompressedServerKey), params: ShortintKeySwitchingParameters, ) -> Self

where InputEncryptionKey: Into<SecretEncryptionKeyView<'input_key>>,

pub fn decompress(&self) -> KeySwitchingKey

pub fn into_raw_parts( self, ) -> (CompressedKeySwitchingKeyMaterial, CompressedServerKey, Option<CompressedServerKey>)

Deconstruct a CompressedKeySwitchingKey into its constituents.

pub fn from_raw_parts( key_switching_key_material: CompressedKeySwitchingKeyMaterial, dest_server_key: CompressedServerKey, src_server_key: Option<CompressedServerKey>, ) -> Self

Construct a CompressedKeySwitchingKey from its constituents.

Panics

Panics if the provided raw parts are not compatible with each other, i.e.:

if the provided source CompressedServerKey ciphertext LweDimension does not match the input LweDimension of the SeededLweKeyswitchKeyOwned in the provided CompressedKeySwitchingKeyMaterial or if the provided destination CompressedServerKey ciphertext LweDimension does not match the output LweDimension of the SeededLweKeyswitchKeyOwned in the provided CompressedKeySwitchingKeyMaterial.

Trait Implementations

Formats the value using the given formatter.

impl Deprecable for CompressedKeySwitchingKey

const TYPE_NAME: &'static str = "CompressedKeySwitchingKey"

const MIN_SUPPORTED_APP_VERSION: &'static str = "TFHE-rs v0.10"

fn error() -> DeprecatedVersionError

impl<'de> Deserialize<'de> for CompressedKeySwitchingKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for CompressedKeySwitchingKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Unversionize for CompressedKeySwitchingKey

where CompressedKeySwitchingKeyVersions: VersionsDispatch<Self>,

fn unversionize( versioned: Self::VersionedOwned, ) -> Result<Self, UnversionizeError>

Creates an object from a versioned enum, and eventually upgrades from previous variants.

impl UnversionizeVec for CompressedKeySwitchingKey

where CompressedKeySwitchingKeyVersions: VersionsDispatch<Self>,

fn unversionize_vec( versioned: Self::VersionedVec, ) -> Result<Vec<Self>, UnversionizeError>

impl Version for CompressedKeySwitchingKey

where CompressedKeySwitchingKeyMaterial: VersionizeOwned + Unversionize + Versionize, CompressedServerKey: VersionizeOwned + Unversionize + Versionize, Option<CompressedServerKey>: VersionizeOwned + Unversionize + Versionize,

type Ref<'vers> = CompressedKeySwitchingKeyVersion<'vers>

type Owned = CompressedKeySwitchingKeyVersionOwned

impl Versionize for CompressedKeySwitchingKey

where CompressedKeySwitchingKeyVersions: VersionsDispatch<Self>,

type Versioned<'vers> = <CompressedKeySwitchingKeyVersions as VersionsDispatch<CompressedKeySwitchingKey>>::Ref<'vers>

The equivalent versioned type. It should have a variant for each version. It may own the underlying data or only hold a read-only reference to it.

fn versionize(&self) -> Self::Versioned<'_>

Wraps the object into a versioned enum with a variant for each version. This will use references on the underlying types if possible.

impl VersionizeOwned for CompressedKeySwitchingKey

where CompressedKeySwitchingKeyVersions: VersionsDispatch<Self>,

type VersionedOwned = <CompressedKeySwitchingKeyVersions as VersionsDispatch<CompressedKeySwitchingKey>>::Owned

fn versionize_owned(self) -> Self::VersionedOwned

Wraps the object into a versioned enum with a variant for each version. This will clone the underlying types.

impl VersionizeSlice for CompressedKeySwitchingKey

where CompressedKeySwitchingKeyVersions: VersionsDispatch<Self>,

type VersionedSlice<'vers> = Vec<<CompressedKeySwitchingKey as Versionize>::Versioned<'vers>>
