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

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<E: Clone + Pairing> Clone for VerifyingKey<E>where E::G1Affine: Clone, E::G2Affine: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug + Pairing> Debug for VerifyingKey<E>where E::G1Affine: Debug, E::G2Affine: Debug,

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

Formats the value using the given formatter.

impl<E: Pairing> Default for VerifyingKey<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<VerifyingKey<E>> for VerifyingKey<E>where E::G1Affine: PartialEq, E::G2Affine: PartialEq,

fn eq(&self, other: &VerifyingKey<E>) -> 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.
