impl R1CSToQAP for LibsnarkReduction

source§

fn instance_map_with_evaluation<F: PrimeField, D: EvaluationDomain<F>>( cs: ConstraintSystemRef<F>, t: &F ) -> R1CSResult<(Vec<F>, Vec<F>, Vec<F>, F, usize, usize)>

Computes a QAP instance corresponding to the R1CS instance defined by cs.
source§

fn witness_map_from_matrices<F: PrimeField, D: EvaluationDomain<F>>( matrices: &ConstraintMatrices<F>, num_inputs: usize, num_constraints: usize, full_assignment: &[F] ) -> R1CSResult<Vec<F>>

Computes a QAP witness corresponding to the R1CS witness defined by cs.
source§

fn h_query_scalars<F: PrimeField, D: EvaluationDomain<F>>( max_power: usize, t: F, zt: F, delta_inverse: F ) -> Result<Vec<F>, SynthesisError>

Computes the exponents that the generator uses to calculate base elements which the prover later uses to compute h(x)t(x)/delta.
source§

fn witness_map<F: PrimeField, D: EvaluationDomain<F>>( prover: ConstraintSystemRef<F> ) -> Result<Vec<F>, SynthesisError>
