Struct IndexComposition

source
pub struct IndexComposition<C, const N: usize> { /* private fields */ }
Expand description

An adapter which allows evaluating a composition over a larger query by indexing into it. See index_composition for a factory method.

impl<C: Clone, const N: usize> Clone for IndexComposition<C, N>

source§

fn clone(&self) -> IndexComposition<C, N>

Returns a copy of the value. Read more
1.6.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl<P: PackedField, C: CompositionPoly<P>, const N: usize> CompositionPoly<P> for IndexComposition<C, N>

source§

fn n_vars(&self) -> usize

The number of variables.
source§

fn degree(&self) -> usize

Total degree of the polynomial.
source§

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. Read more
source§

fn binary_tower_level(&self) -> usize

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

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. Read more
