CommitterKey is used to commit to, and create evaluation proofs for, a given polynomial.

Fields

comm_key: Vec<G>

The key used to commit to polynomials.

h: G

A random group generator.

A random group generator that is to be used to make a commitment hiding.

max_degree: usize

Trait Implementations

impl<G: AffineRepr> CanonicalDeserialize for CommitterKey<G>

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<G: AffineRepr> CanonicalSerialize for CommitterKey<G>

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<G: AffineRepr> Clone for CommitterKey<G>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<G: AffineRepr> Debug for CommitterKey<G>

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

Formats the value using the given formatter.

impl<G: AffineRepr> Default for CommitterKey<G>

fn default() -> Self

Returns the “default value” for a type.

impl<G: AffineRepr> Hash for CommitterKey<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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<G: AffineRepr> PCCommitterKey for CommitterKey<G>

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 committer key.

impl<G: AffineRepr> PCPreparedVerifierKey<CommitterKey<G>> for PreparedVerifierKey<G>

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

prepare PreparedVerifierKey from VerifierKey

impl<G: AffineRepr> Valid for CommitterKey<G>

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.
