Struct AdditiveRsEncoder 

pub struct AdditiveRsEncoder<F, Ntt = PolyBasisNtt> { /* private fields */ }

Reed–Solomon over the additive NTT domain.

The message holds the low-index novel-basis coefficients of each column, so the codeword is the evaluation of f̂(Ŵ_0(x), …, Ŵ_{k−1}(x)) on S_{k + log_inv_rate}.

The alphabet is BinaryField128, where PolyBasisNtt is the faster transform and falls back to LchNtt on a target without a carryless multiply, so it is the default.

F is phantom: Encoder is only implemented below for F = BinaryField128, and stays that way as long as the alphabet is fixed (D9), so the parameter carries no other instance.

Trait Implementations

impl<F: Clone, Ntt: Clone> Clone for AdditiveRsEncoder<F, Ntt>

fn clone(&self) -> AdditiveRsEncoder<F, Ntt>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug, Ntt: Debug> Debug for AdditiveRsEncoder<F, Ntt>

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

Formats the value using the given formatter.

impl<F: Default, Ntt: Default> Default for AdditiveRsEncoder<F, Ntt>

fn default() -> AdditiveRsEncoder<F, Ntt>

Returns the “default value” for a type.

impl<Ntt: AdditiveNtt<BinaryField128> + Sync> Encoder<BinaryField128> for AdditiveRsEncoder<BinaryField128, Ntt>

The alphabet is fixed at BinaryField128 (D9), as Encoder requires of every impl outside p3-commit’s blanket one.

fn encode_batch( &self, message: RowMajorMatrix<BinaryField128>, log_inv_rate: usize, ) -> RowMajorMatrix<BinaryField128>

Encodes each column of message into a codeword.
