Expand description

Errors that can occur while verifying a PCZT bundle.

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.
§

InvalidExtractedNoteCommitment

The output note’s components do not produce the expected cmu.

§

InvalidNullifier

The spent note’s components do not produce the expected nullifier.

§

InvalidRandomizedVerificationKey

The Spend’s FVK and alpha do not produce the expected rk.

§

InvalidValueCommitment

The spend or output’s cv does not match the note value and rcv.

§

MismatchedFullViewingKey

The spend’s proof_generation_key field does not match the provided FVK.

§

MissingProofGenerationKey

Dummy notes must have their proof_generation_key field set in order to be verified.

§

MissingRandomSeed

nullifier verification requires rseed to be set.

§

MissingRecipient

nullifier verification requires recipient to be set.

§

MissingSpendAuthRandomizer

rk verification requires alpha to be set.

§

MissingValue

Verification requires all value fields to be set.

§

MissingValueCommitTrapdoor

cv verification requires rcv to be set.

§

MissingWitness

nullifier verification requires witness to be set.

§

WrongFvkForNote

The provided fvk does not own the spent note.
