    pub_params: &<FallbackPoSt<'a, Tree> as ProofScheme<'a>>::PublicParams,
    partition_k: Option<usize>
) -> Result<Vec<Fr>>

generate_public_inputs generates public inputs suitable for use as input during verification of a proof generated from this CompoundProof’s bellperson::Circuit (C). These inputs correspond to those allocated when C is synthesized.

    partition_k: Option<usize>
) -> Result<FallbackPoStCircuit<Tree>>

circuit constructs an instance of this CompoundProof’s bellperson::Circuit. circuit takes PublicInputs, PublicParams, and Proof from this CompoundProof’s proof::ProofScheme (S) and uses them to initialize Circuit fields which will be used to construct public and private inputs during circuit synthesis.

circuit_proof creates and synthesizes a circuit from concrete params/inputs, then generates a groth proof from it. It returns a groth proof. circuit_proof is used internally and should neither be called nor implemented outside of default trait methods.

fn aggregate_proofs(
    prover_srs: &ProverSRS<Bls12>,
    hashed_seeds_and_comm_rs: &[u8],
    proofs: &[Proof<Bls12>]

Given a prover_srs key, a list of groth16 proofs, and an ordered list of seeds (used to derive the PoRep challenges) hashed pair-wise with the comm_rs using sha256, aggregate them all into an AggregateProof type.

fn verify_aggregate_proofs(

    R: RngCore, 

If the rng option argument is set, parameters will be generated using it. This is used for testing only, or where parameters are otherwise unavailable (e.g. benches). If rng is not set, an error will result if parameters are not present.
