Fields

g: E::G1Affine

The generator of G1.

gamma_g: E::G1Affine

The generator of G1 that is used for making a commitment hiding.

h: E::G2Affine

The generator of G2.

beta_h: E::G2Affine

\beta times the above generator of G2.

prepared_h: E::G2Prepared

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> 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>>
