Struct poly_commit::KzgParams

pub struct KzgParams<P: Pairing> { /* private fields */ }

Kate polynomial commitment params used for prover polynomial domain and proof verification

Implementations

impl<P: Pairing> KzgParams<P>

pub fn setup(k: u64, r: P::ScalarField) -> Self

pub fn commit( &self, poly: &Coefficients<P::ScalarField> ) -> Result<Commitment<P::G1Affine>, Error>

pub fn commit_key(&self) -> &Vec<P::G1Affine>

pub fn opening_key(&self) -> P::G2Affine

pub fn beta_h(&self) -> P::G2Affine

pub fn max_degree(&self) -> usize

pub fn trim(&self, truncated_degree: usize) -> Self

pub fn create_witness( &self, poly: &Coefficients<P::ScalarField>, at: P::ScalarField ) -> Witness<P>

pub fn compute_aggregate_witness( &self, polynomials: &[Coefficients<P::ScalarField>], point: &P::ScalarField, v_challenge: &P::ScalarField ) -> Coefficients<P::ScalarField>

Computes a single witness for multiple polynomials at the same point, by taking a random linear combination of the individual witnesses. We apply the same optimization mentioned in when computing each witness; removing f(z).

Trait Implementations

impl<P: Clone + Pairing> Clone for KzgParams<P>where P::G1Affine: Clone, P::G2Affine: Clone,

fn clone(&self) -> KzgParams<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: Debug + Pairing> Debug for KzgParams<P>where P::G1Affine: Debug, P::G2Affine: Debug,

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

Formats the value using the given formatter.

impl<P: Pairing> Decode for KzgParams<P>where Vec<P::G1Affine>: Decode, P::G2Affine: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<P: Default + Pairing> Default for KzgParams<P>where P::G1Affine: Default, P::G2Affine: Default,

fn default() -> KzgParams<P>

Returns the “default value” for a type.

impl<P: Pairing> Encode for KzgParams<P>where Vec<P::G1Affine>: Encode, P::G2Affine: Encode,

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<P: PartialEq + Pairing> PartialEq<KzgParams<P>> for KzgParams<P>where P::G1Affine: PartialEq, P::G2Affine: PartialEq,

fn eq(&self, other: &KzgParams<P>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
