Struct GLWETensorKeyLayout 

pub struct GLWETensorKeyLayout {
    pub n: Degree,
    pub base2k: Base2K,
    pub k: TorusPrecision,
    pub rank: Rank,
    pub dnum: Dnum,
    pub dsize: Dsize,
}

Plain-data descriptor for a GLWETensorKey carrying only the layout parameters (no backing buffer).

Implements LWEInfos, GLWEInfos and GGLWEInfos so it can be passed to any generic constructor that needs layout information. The rank_in is derived from rank as max(1, rank*(rank+1)/2).

Fields

n: Degree

base2k: Base2K

k: TorusPrecision

rank: Rank

dnum: Dnum

dsize: Dsize

Trait Implementations

impl Clone for GLWETensorKeyLayout

fn clone(&self) -> GLWETensorKeyLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GLWETensorKeyLayout

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

Formats the value using the given formatter.

impl DeclaredK for GLWETensorKeyLayout

fn k(&self) -> TorusPrecision

impl GGLWEInfos for GLWETensorKeyLayout

fn rank_in(&self) -> Rank

fn dsize(&self) -> Dsize

fn rank_out(&self) -> Rank

fn dnum(&self) -> Dnum

fn gglwe_layout(&self) -> GGLWELayout

impl GLWEInfos for GLWETensorKeyLayout

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 GLWETensorKeyLayout

fn n(&self) -> Degree

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

fn base2k(&self) -> Base2K

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

fn size(&self) -> usize

Returns the number of limbs, i.e. ceil(k / base2k).

fn log_n(&self) -> usize

Returns log2(n).

fn max_k(&self) -> TorusPrecision

Returns the maximum torus precision representable with the current limb decomposition.

fn lwe_layout(&self) -> LWELayout

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

impl PartialEq for GLWETensorKeyLayout

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
