Fields
prepared_g: Vec<<PG as PairingGadget<TargetCurve, <BaseCurve as PairingEngine>::Fr>>::G1Gadget, Global>
Generator of G1.
prepared_h: <PG as PairingGadget<TargetCurve, <BaseCurve as PairingEngine>::Fr>>::G2PreparedGadget
Generator of G2.
prepared_beta_h: <PG as PairingGadget<TargetCurve, <BaseCurve as PairingEngine>::Fr>>::G2PreparedGadget
Generator of G1, times first monomial.
prepared_degree_bounds_and_shift_powers: Option<Vec<(usize, FpGadget<<BaseCurve as PairingEngine>::Fr>, Vec<<PG as PairingGadget<TargetCurve, <BaseCurve as PairingEngine>::Fr>>::G1Gadget, Global>), Global>>
