Struct ark_poly_commit::ipa_pc::Randomness

pub struct Randomness<G: AffineRepr> {
    pub rand: G::ScalarField,
    pub shifted_rand: Option<G::ScalarField>,
}

Randomness hides the polynomial inside a commitment and is outputted by InnerProductArg::commit.

Fields

rand: G::ScalarField

Randomness is some scalar field element.

shifted_rand: Option<G::ScalarField>

Randomness applied to the shifted commitment is some scalar field element.

fn serialize_compressed<W>(&self, writer: W) -> Result<(), SerializationError>where W: Write,

fn compressed_size(&self) -> usize

fn serialize_uncompressed<W>(&self, writer: W) -> Result<(), SerializationError>where W: Write,

fn uncompressed_size(&self) -> usize

impl<G: AffineRepr> Clone for Randomness<G>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<G: AffineRepr> Debug for Randomness<G>

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

Formats the value using the given formatter.

impl<G: AffineRepr> Default for Randomness<G>

fn default() -> Self

Returns the “default value” for a type.

impl<G: AffineRepr> Hash for Randomness<G>

fn hash<__HG>(&self, __state: &mut __HG)where __HG: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<G: AffineRepr> PCRandomness for Randomness<G>

fn empty() -> Self

Outputs empty randomness that does not hide the commitment.

fn rand<R: RngCore>( _: usize, has_degree_bound: bool, _: Option<usize>, rng: &mut R ) -> Self

Samples randomness for commitments; num_queries specifies the number of queries that the commitment will be opened at. has_degree_bound indicates that the corresponding commitment has an enforced num_vars specifies the number of variables for multivariate commitment. strict degree bound.

impl<G: AffineRepr> PartialEq<Randomness<G>> for Randomness<G>

fn eq(&self, other: &Self) -> 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.

impl<G: AffineRepr> Valid for Randomness<G>
