#[non_exhaustive]
pub enum VerificationError { ChallengeMismatch, LenMismatch { collection: &'static str, expected: usize, actual: usize, }, }
Expand description

Error verifying base proofs, such as RingProof, LogEqualityProof or ProofOfPossession.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

ChallengeMismatch

Restored challenge scalar does not match the one provided in the proof.

This error most likely means that the proof itself is malformed, or that it was created for a different context than it is being verified for.

§

LenMismatch

Fields

§collection: &'static str

Human-readable collection name, such as “public keys”.

§expected: usize

Expected size of the collection.

§actual: usize

Actual size of the collection.

A collection (e.g., number of responses in a RingProof) has a different size than expected.

This error most likely means that the proof is malformed.
