Struct GLWEAutomorphismKeyLayout 

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

Plain-data descriptor for a GLWEAutomorphismKey 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. For an automorphism key rank_in == rank_out.

Fields

n: Degree

base2k: Base2K

k: TorusPrecision

rank: Rank

dnum: Dnum

dsize: Dsize

Trait Implementations

impl Clone for GLWEAutomorphismKeyLayout

fn clone(&self) -> GLWEAutomorphismKeyLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GLWEAutomorphismKeyLayout

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

Formats the value using the given formatter.

impl DeclaredK for GLWEAutomorphismKeyLayout

fn k(&self) -> TorusPrecision

impl GGLWEInfos for GLWEAutomorphismKeyLayout

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 GLWEAutomorphismKeyLayout

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 GLWEAutomorphismKeyLayout

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 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 GLWEAutomorphismKeyLayout

fn eq(&self, other: &GLWEAutomorphismKeyLayout) -> 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.
