Struct binius_core::polynomial::multivariate::IdentityCompositionPoly

pub struct IdentityCompositionPoly;

Identity composition function $g(X) = X$.

Trait Implementations

impl Clone for IdentityCompositionPoly

fn clone(&self) -> IdentityCompositionPoly

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: PackedField> CompositionPoly<P> for IdentityCompositionPoly

fn n_vars(&self) -> usize

The number of variables.

fn degree(&self) -> usize

Total degree of the polynomial.

fn evaluate(&self, query: &[P]) -> Result<P, Error>

Evaluates the polynomial using packed values, where each packed value may contain multiple scalar values. The evaluation follows SIMD semantics, meaning that operations are performed element-wise across corresponding scalar values in the packed values.

fn binary_tower_level(&self) -> usize

Returns the maximum binary tower level of all constants in the arithmetic expression.

fn sparse_batch_evaluate( &self, sparse_batch_query: &[&[P]], evals: &mut [P] ) -> Result<(), Error>

Batch evaluation that admits non-strided argument layout. sparse_batch_query is a slice of slice references of equal length, which furthermore should equal the length of evals parameter.

impl Debug for IdentityCompositionPoly

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

Formats the value using the given formatter.
