Fields

row_len: usize

The length of the pseudo NTT’s input.

codeword_len: usize

The length of the pseudo NTT’s output.

depth: usize

The number of steps where NTT is performed recursively.

base_len: usize

The number of columns of the base matrix.

base_dim: usize

The number of rows of the base matrix, always a power of 2.

base_dim_log2: u32

log2 of the number of rows of the base matrix.

base_dim_mask: usize

The mask to compute i % base_dim.

base_matrix: Vec<Vec<PnttInt>>

The base matrix of the pseudo NTT.

butterfly_twiddles: Vec<Vec<[[PnttInt; 8]; 7]>>

Precomputed twiddles for every stage that already contain the relevant root-of-unity factor. This lets the butterfly apply a single multiplication per term instead of two.

Implementations

impl<C: Config> Radix8PnttParams<C>

pub fn new( row_len: usize, depth: usize, rep_factor: usize, ) -> Result<Self, ZipError>

Precompute pseudo NTT parameters.

Trait Implementations

impl<C: Clone + Config> Clone for Radix8PnttParams<C>

fn clone(&self) -> Radix8PnttParams<C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: Debug + Config> Debug for Radix8PnttParams<C>

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

Formats the value using the given formatter.

impl<C: PartialEq + Config> PartialEq for Radix8PnttParams<C>

fn eq(&self, other: &Radix8PnttParams<C>) -> 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.
