Struct binius_core::polynomial::multilinear_extension::MultilinearExtensionSpecialized

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

A wrapper type for MultilinearExtension that specializes to a packed extension field type.

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