Struct MLEEmbeddingAdapter

pub struct MLEEmbeddingAdapter<P, PE, Data = Vec<P>>(/* private fields */)
where
    P: PackedField,
    PE: PackedField,
    PE::Scalar: ExtensionField<P::Scalar>,
    Data: Deref<Target = [P]>;

An adapter for MultilinearExtension that implements MultilinearPoly over a packed extension field.

This struct implements MultilinearPoly for an extension field of the base field that the multilinear extension is defined over.

fn n_vars(&self) -> usize

Number of variables.

fn evaluate_on_hypercube(&self, index: usize) -> Result<PE::Scalar, Error>

Get the evaluations of the polynomial at a vertex of the hypercube.

fn evaluate_on_hypercube_and_scale( &self, index: usize, scalar: PE::Scalar, ) -> Result<PE::Scalar, Error>

Get the evaluations of the polynomial at a vertex of the hypercube and scale the value.

fn evaluate( &self, query: MultilinearQueryRef<'_, PE>, ) -> Result<PE::Scalar, Error>

fn evaluate_partial_low( &self, query: MultilinearQueryRef<'_, PE>, ) -> Result<MultilinearExtension<PE>, Error>

fn evaluate_partial_high( &self, query: MultilinearQueryRef<'_, PE>, ) -> Result<MultilinearExtension<PE>, Error>

where P: PackedField + PartialEq, PE: PackedField + PartialEq, PE::Scalar: ExtensionField<P::Scalar>, Data: Deref<Target = [P]> + PartialEq,

fn eq(&self, other: &MLEEmbeddingAdapter<P, PE, Data>) -> 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.
