Implementations

impl<'a, BE: Backend + 'a> GGSWCompressedBackendRef<'a, BE>

pub fn into_inner(self) -> GGSWCompressed<BE::BufRef<'a>, BE::ZnxWord>

pub fn at_view(&self, row: usize, col: usize) -> GLWECompressedViewRef<'_, BE>

Methods from Deref<Target = GGSWCompressed<BE::BufRef<'a>, BE::ZnxWord>>

pub fn at(&self, row: usize, col: usize) -> GLWECompressed<&[u8], W>

Returns an immutably-borrowed compressed GLWE at the given row and column.

Trait Implementations

impl<'a, BE: Backend + 'a> Deref for GGSWCompressedBackendRef<'a, BE>

type Target = GGSWCompressed<<BE as Backend>::BufRef<'a>, <BE as Backend>::ZnxWord>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, BE: Backend + 'a> GGSWInfos for GGSWCompressedBackendRef<'a, BE>

fn k_aux(&self) -> TorusPrecision

Auxiliary guard precision (in bits) stored below the gadget region and used for noise management during key operations. Free value, need not be a multiple of base2k.

fn dnum(&self) -> Dnum

Returns the number of gadget-decomposition rows.

fn dsize(&self) -> Dsize

Returns the decomposition digit size.

fn ggsw_layout(&self) -> GGSWLayout

Returns a plain-data GGSWLayout snapshot of the current parameters.

impl<'a, BE: Backend + 'a> GLWEInfos for GGSWCompressedBackendRef<'a, BE>

fn rank(&self) -> Rank

Returns the GLWE rank (number of mask polynomials).

fn glwe_layout(&self) -> GLWELayout

Returns a plain-data GLWELayout snapshot of the current parameters.

impl<'a, BE: Backend + 'a> LWEInfos for GGSWCompressedBackendRef<'a, BE>

fn base2k(&self) -> Base2K

Returns the base-2-log of the limb width used for the RNS/CRT representation.

fn n(&self) -> Degree

Returns the LWE dimension, i.e. the number of mask elements (= GLWE ring degree N).

fn max_size(&self) -> usize

Returns the allocated limb capacity of the backing container: the physical width operations may compute at (size() <= max_size()). Together with k() this fully describes an object: k is the claimed precision and max_size the allocation. Layout/spec types without a buffer report their metadata-derived width.

fn k(&self) -> TorusPrecision

Returns the Torus precision used by the object.

fn log_n(&self) -> usize

Returns log2(n).

fn max_k(&self) -> TorusPrecision

Returns the Torus precision the allocation can hold (Self::max_size * base2k).

fn size(&self) -> usize

Returns the limb width generic core operations should process.

fn lwe_layout(&self) -> LWELayout

Returns a plain-data LWELayout snapshot of the current parameters.
