CommitterUnionKey is a union of CommitterKeys, useful for multi-circuit batch proofs.

Fields

powers_of_beta_g: Option<&'a Vec<E::G1Affine>>

The key used to commit to polynomials.

lagrange_bases_at_beta_g: BTreeMap<usize, &'a Vec<E::G1Affine>>

The key used to commit to polynomials in Lagrange basis.

powers_of_beta_times_gamma_g: Option<&'a Vec<E::G1Affine>>

The key used to commit to hiding polynomials.

shifted_powers_of_beta_g: Option<&'a 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, &'a 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.
