Struct ark_poly_commit::ipa_pc::Randomness

pub struct Randomness<G: AffineCurve> {
    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.

Trait Implementations

impl<G: AffineCurve> CanonicalDeserialize for Randomness<G>

fn deserialize<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads Self from reader.

fn deserialize_uncompressed<R: Read>(
    reader: R
) -> Result<Self, SerializationError>

Reads Self from reader without compression.

fn deserialize_unchecked<R: Read>(reader: R) -> Result<Self, SerializationError>

Reads self from reader without compression, and without performing validity checks. Should be used only when the input is trusted.

impl<G: AffineCurve> CanonicalSerialize for Randomness<G>

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

Serializes self into writer. It is left up to a particular type for how it strikes the serialization efficiency vs compression tradeoff. For standard types (e.g. bool, lengths, etc.) typically an uncompressed form is used, whereas for algebraic types compressed forms are used.

fn serialized_size(&self) -> usize

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

Serializes self into writer without compression.

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

Serializes self into writer without compression, and without performing validity checks. Should be used only when there is no danger of adversarial manipulation of the output.

fn uncompressed_size(&self) -> usize

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

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

Formats the value using the given formatter.

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

fn default() -> Self

Returns the “default value” for a type.

impl<G: AffineCurve> 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, 

Feeds a slice of this type into the given Hasher.

impl<G: AffineCurve> 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: AffineCurve> 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 ==.

#[must_use]

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

This method tests for !=.
