Expand description

Context available to the verification process.

Fields (Non-exhaustive)§

This struct is marked as 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.
§suites: BTreeMap<String, HashSuite<BabyBear>>

A registry of hash functions to be used by the verification process.

§segment_verifier_parameters: Option<SegmentReceiptVerifierParameters>

Parameters for verification of SegmentReceipt.

§succinct_verifier_parameters: Option<SuccinctReceiptVerifierParameters>

Parameters for verification of SuccinctReceipt.

§groth16_verifier_parameters: Option<Groth16ReceiptVerifierParameters>

Parameters for verification of Groth16Receipt.

impl VerifierContext

Source

pub fn empty() -> Self

Create an empty VerifierContext.

Source

pub fn default_hash_suites() -> BTreeMap<String, HashSuite<BabyBear>>

pub fn from_max_po2(po2_max: usize) -> Self

Available on crate feature unstable only.

Construct a verifier context that will accept receipts with control any of the default control ID associated with cycle counts as powers of two (po2) up to the given max inclusive.
