Struct PreparedVerifyingKey

pub struct PreparedVerifyingKey<E: Pairing> {
    pub vk: VerifyingKey<E>,
    pub alpha_g1_beta_g2: E::TargetField,
    pub gamma_g2_neg_pc: E::G2Prepared,
    pub delta_g2_neg_pc: E::G2Prepared,
}

Preprocessed verification key parameters that enable faster verification at the expense of larger size in memory.

Fields

vk: VerifyingKey<E>

The unprepared verification key.

alpha_g1_beta_g2: E::TargetField

The element e(alpha * G, beta * H) in E::GT.

gamma_g2_neg_pc: E::G2Prepared

The element - gamma * H in E::G2, prepared for use in pairings.

delta_g2_neg_pc: E::G2Prepared

The element - delta * H in E::G2, prepared for use in pairings.

Performs copy-assignment from source.

impl<E: Debug + Pairing> Debug for PreparedVerifyingKey<E>

where E::TargetField: Debug, E::G2Prepared: Debug,

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

Formats the value using the given formatter.

impl<E: Pairing> Default for PreparedVerifyingKey<E>

fn default() -> Self

Returns the “default value” for a type.

impl<E: Pairing> From<PreparedVerifyingKey<E>> for VerifyingKey<E>
