Fields

n: Degree

Ring degree.

base2k: Base2K

Base-2-log of the limb width.

dnum: Dnum

Number of gadget-decomposition rows.

k_aux: TorusPrecision

Auxiliary guard precision (torus bits) below the gadget region.

rank: Rank

GLWE rank (number of mask polynomials per row).

dsize: Dsize

Decomposition digit size.

Trait Implementations

impl Clone for GGSWLayout

fn clone(&self) -> GGSWLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for GGSWLayout

impl Debug for GGSWLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for GGSWLayout

impl GGSWInfos for GGSWLayout

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 GLWEInfos for GGSWLayout

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 LWEInfos for GGSWLayout

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.

impl PartialEq for GGSWLayout

fn eq(&self, other: &GGSWLayout) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
