Struct MLEDirectAdapter

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

Trait Implementations

fn clone(&self) -> MLEDirectAdapter<P, Data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P, Data> Debug for MLEDirectAdapter<P, Data>

where P: PackedField + Debug, Data: Deref<Target = [P]> + Debug,

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

Formats the value using the given formatter.

impl<P, Data> From<MultilinearExtension<P, Data>> for MLEDirectAdapter<P, Data>

where P: PackedField, Data: Deref<Target = [P]>,

fn from(inner: MultilinearExtension<P, Data>) -> Self

Converts to this type from the input type.

impl<F, P, Data> MultilinearPoly<P> for MLEDirectAdapter<P, Data>

where F: Field, P: PackedField<Scalar = F> + Debug, Data: Deref<Target = [P]> + Send + Sync + Debug,

fn n_vars(&self) -> usize

Number of variables.

fn log_extension_degree(&self) -> usize

Binary logarithm of the extension degree (always exists because we only support power-of-two extension degrees)

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

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

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

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

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

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

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

fn subcube_inner_products( &self, query: MultilinearQueryRef<'_, P>, subcube_vars: usize, subcube_index: usize, inner_products: &mut [P], ) -> Result<(), Error>

Compute inner products of a multilinear query inside a subcube.

fn subcube_evals( &self, subcube_vars: usize, subcube_index: usize, log_embedding_degree: usize, evals: &mut [P], ) -> Result<(), Error>

Get a subcube of the boolean hypercube of a given size.

fn underlier_data(&self) -> Option<&[u8]>

If available, returns underliers of the data of this multilinear as bytes.

impl<P, Data> PartialEq for MLEDirectAdapter<P, Data>

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

fn eq(&self, other: &MLEDirectAdapter<P, 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.
