pub struct VerifierKey<E: PairingEngine> {

VerifierKey is used to check evaluation proofs for a given commitment.

Fields

vk: VerifierKey<E>

The verification key for the underlying KZG10 scheme.

degree_bounds_and_shift_powers: Option<Vec<(usize, E::G1Affine)>>

Information required to enforce degree bounds. Each pair is of the form (degree_bound, shifting_advice). The vector is sorted in ascending order of degree_bound. This is None if self does not support enforcing any degree bounds.

max_degree: usize

The maximum degree supported by the UniversalParams self was derived from.

supported_degree: usize

The maximum degree supported by the trimmed parameters that self is a part of.

Implementations

impl<E: PairingEngine> VerifierKey<E>

pub fn get_shift_power(&self, bound: usize) -> Option<E::G1Affine>

Find the appropriate shift for the degree bound.

Trait Implementations

impl<E: PairingEngine> CanonicalDeserialize for VerifierKey<E>

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<E: PairingEngine> CanonicalSerialize for VerifierKey<E>

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<E: PairingEngine> Clone for VerifierKey<E>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: PairingEngine> Debug for VerifierKey<E>

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

Formats the value using the given formatter.

impl<E: PairingEngine> Default for VerifierKey<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: PairingEngine> PCPreparedVerifierKey<VerifierKey<E>> for PreparedVerifierKey<E>

fn prepare(vk: &VerifierKey<E>) -> Self

prepare PreparedVerifierKey from VerifierKey

impl<E: PairingEngine> PCVerifierKey for VerifierKey<E>

fn max_degree(&self) -> usize

Outputs the maximum degree supported by the universal parameters Self was derived from.

fn supported_degree(&self) -> usize

Outputs the maximum degree supported by the verifier key.

impl<E: PairingEngine> ToBytes for VerifierKey<E>

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

Serializes self into writer.

impl<E: PairingEngine> ToConstraintField<<<E as PairingEngine>::Fq as Field>::BasePrimeField> for VerifierKey<E> where
    E::G1Affine: ToConstraintField<<E::Fq as Field>::BasePrimeField>,
    E::G2Affine: ToConstraintField<<E::Fq as Field>::BasePrimeField>, 

fn to_field_elements(&self) -> Option<Vec<<E::Fq as Field>::BasePrimeField>>
