    pub gamma_g2_neg_pc: E::G2Prepared,
    pub delta_g2_neg_pc: E::G2Prepared,

Preprocessed verification key parameters that enable faster verification at the expense of larger size in memory.

Fields

vk: VerifyingKey<E>

The unprepared verification key.

alpha_g1_beta_g2: E::TargetField

The element e(alpha * G, beta * H) in E::GT.

gamma_g2_neg_pc: E::G2Prepared

The element - gamma * H in E::G2, prepared for use in pairings.

delta_g2_neg_pc: E::G2Prepared

The element - delta * H in E::G2, prepared for use in pairings.

Trait Implementations

impl<E: Pairing> CanonicalDeserialize for PreparedVerifyingKey<E>

fn deserialize_with_mode<R: Read>( reader: R, compress: Compress, validate: Validate, ) -> Result<Self, SerializationError>

The general deserialize method that takes in customization flags.

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

where R: Read,

Reads Self from reader using the compressed form if applicable. Performs validation if applicable.

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

where R: Read,

Reads Self from reader using the compressed form if applicable, without validating the deserialized value.

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

where R: Read,

Reads Self from reader using the uncompressed form. Performs validation if applicable.

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

where R: Read,

Reads Self from reader using the uncompressed form, without validating the deserialized value.

impl<E: Pairing> CanonicalSerialize for PreparedVerifyingKey<E>

fn serialize_with_mode<W: Write>( &self, writer: W, compress: Compress, ) -> Result<(), SerializationError>

The general serialize method that takes in customization flags.

fn serialized_size(&self, compress: Compress) -> usize

Returns the size in bytes of the serialized version of self with the given compression mode.

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

where W: Write,

Serializes self into writer using the compressed form if applicable.

fn compressed_size(&self) -> usize

Returns the size in bytes of the compressed serialized version of self.

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

where W: Write,

Serializes self into writer using the uncompressed form.

fn uncompressed_size(&self) -> usize

Returns the size in bytes of the uncompressed serialized version of self.

impl<E: Clone + Pairing> Clone for PreparedVerifyingKey<E>

where E::TargetField: Clone, E::G2Prepared: Clone,

fn clone(&self) -> PreparedVerifyingKey<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug + Pairing> Debug for PreparedVerifyingKey<E>

where E::TargetField: Debug, E::G2Prepared: Debug,

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

Formats the value using the given formatter.

impl<E: Pairing> Default for PreparedVerifyingKey<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: Pairing> From<PreparedVerifyingKey<E>> for VerifyingKey<E>

fn from(other: PreparedVerifyingKey<E>) -> Self

Converts to this type from the input type.

impl<E: Pairing> From<VerifyingKey<E>> for PreparedVerifyingKey<E>

fn from(other: VerifyingKey<E>) -> Self

Converts to this type from the input type.

impl<E: PartialEq + Pairing> PartialEq for PreparedVerifyingKey<E>

where E::TargetField: PartialEq, E::G2Prepared: PartialEq,

fn eq(&self, other: &PreparedVerifyingKey<E>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<E: Pairing> Valid for PreparedVerifyingKey<E>

const TRIVIAL_CHECK: bool

Whether the check method is trivial (i.e. always returns Ok(())). If this is true, the batch_check method will skip all checks and return Ok(()). This should be set to true for types where check is trivial, e.g. integers, field elements, etc. This is false by default. This is primarily an optimization to skip unnecessary checks in batch_check.

fn check(&self) -> Result<(), SerializationError>

Checks whether self is valid. If self is valid, returns Ok(()). Otherwise, returns an error describing the failure. This method is called by deserialize_with_mode if validate is Validate::Yes.

fn batch_check<'a>( batch: impl Iterator<Item = &'a Self> + Send, ) -> Result<(), SerializationError>

where Self: 'a,

Checks whether all items in batch are valid. If all items are valid, returns Ok(()). Otherwise, returns an error describing the first failure.
