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

Fields

powers_of_beta_g: Vec<E::G1Affine>

The key used to commit to polynomials.

lagrange_bases_at_beta_g: BTreeMap<usize, Vec<E::G1Affine>>

The key used to commit to polynomials in Lagrange basis.

powers_of_beta_times_gamma_g: Vec<E::G1Affine>

The key used to commit to hiding polynomials.

shifted_powers_of_beta_g: Option<Vec<E::G1Affine>>

The powers used to commit to shifted polynomials. This is None if self does not support enforcing any degree bounds.

shifted_powers_of_beta_times_gamma_g: Option<BTreeMap<usize, Vec<E::G1Affine>>>

The powers used to commit to shifted hiding polynomials. This is None if self does not support enforcing any degree bounds.

enforced_degree_bounds: Option<Vec<usize>>

The degree bounds that are supported by self. Sorted in ascending order from smallest bound to largest bound. This is None if self does not support enforcing any degree bounds.

Trait Implementations

impl<E: Debug + PairingEngine> Debug for CommitterKey<E>

where E::G1Affine: Debug,

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

Formats the value using the given formatter.

impl<E: PairingEngine> FromBytes for CommitterKey<E>

fn read_le<R: Read>(reader: R) -> Result<Self>

Reads Self from reader as little-endian bytes.

fn from_bytes_le(bytes: &[u8]) -> Result<Self, Error>

where Self: Sized,

Returns Self from a byte array in little-endian order.

fn from_bytes_le_unchecked(bytes: &[u8]) -> Result<Self, Error>

where Self: Sized,

Same behavior as Self::from_bytes_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_unchecked<R>(reader: R) -> Result<Self, Error>

where R: Read, Self: Sized,

Same behavior as Self::read_le but avoids costly checks. This shall only be called when deserializing from a trusted source, such as local storage.

fn read_le_with_unchecked<R>(reader: R, unchecked: bool) -> Result<Self, Error>

where R: Read, Self: Sized,

Helper function that deserializes either unchecked or checked based on the given boolean flag.

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

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

Writes self into writer as little-endian bytes.

fn to_bytes_le(&self) -> Result<Vec<u8>, Error>

where Self: Sized,

Returns self as a byte array in little-endian order.
