Struct Groth16Receipt 

#[non_exhaustive]
pub struct Groth16Receipt<Claim> {
    pub seal: Vec<u8>,
    pub claim: MaybePruned<Claim>,
    pub verifier_parameters: Digest,
}

A receipt composed of a Groth16 over the BN_254 curve

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

seal: Vec<u8>

A Groth16 proof of a zkVM execution with the associated claim.

claim: MaybePruned<Claim>

ReceiptClaim containing information about the execution that this receipt proves.

verifier_parameters: Digest

A digest of the verifier parameters that can be used to verify this receipt.

Acts as a fingerprint to identity differing proof system or circuit versions between a prover and a verifier. Is not intended to contain the full verifier parameters, which must be provided by a trusted source (e.g. packaged with the verifier code).

Implementations

impl<Claim> Groth16Receipt<Claim>

pub fn new( seal: Vec<u8>, claim: MaybePruned<Claim>, verifier_parameters: Digest, ) -> Self

Create a Groth16Receipt from the given seal, claim, and verifier parameters digest.

pub fn verify_integrity(&self) -> Result<(), VerificationError>

where Claim: Digestible + Debug,

Verify the integrity of this receipt, ensuring the claim is attested to by the seal.

pub fn verify_integrity_with_context( &self, ctx: &VerifierContext, ) -> Result<(), VerificationError>

where Claim: Digestible + Debug,

Verify the integrity of this receipt, ensuring the claim is attested to by the seal.

pub fn into_unknown(self) -> Groth16Receipt<Unknown>

where Claim: Digestible,

Prunes the claim, retaining its digest, and converts into a Groth16Receipt with an unknown claim type. Can be used to get receipts of a uniform type across heterogeneous claims.

pub fn seal_size(&self) -> usize

Number of bytes used by the seal for this receipt.
