Struct ExtendedWitness

Source 
pub struct ExtendedWitness<G: CommitmentCurve, W: Witness<G>> {
    pub witness: W,
    pub extended: BTreeMap<usize, Evaluations<G::ScalarField, Radix2EvaluationDomain<G::ScalarField>>>,
}
Expand description

This structure represents a witness extended with extra columns that are added by quadraticization

Fields§

§witness: W

This is the original witness, without quadraticization

§extended: BTreeMap<usize, Evaluations<G::ScalarField, Radix2EvaluationDomain<G::ScalarField>>>

Extra columns added by quadraticization to lower the degree of expressions to 2

Implementations§

Source§

impl<G: CommitmentCurve, W: Witness<G>> ExtendedWitness<G, W>

Source

pub fn is_extended(&self) -> bool

Return true if the no extra columns are added by quadraticization

Can be used to know if the extended witness columns are already computed, to avoid overriding them
