Expand description

Errors that may occur during proof verification. Most of the errors types simply indicate that the proof is invalid with respect to the statement being verified, and the exact error type can be used for debugging.

Variants

DuplicateKey(Vec<u8, Global>)

The statement being verified contains multiple key-value pairs with the same key. The parameter is the duplicated key.

Tuple Fields of DuplicateKey

0: Vec<u8, Global>
ExtraneousNode

The proof contains at least one extraneous node.

ExtraneousValue(Vec<u8, Global>)

The proof contains at least one extraneous value which should have been omitted from the proof.

Tuple Fields of ExtraneousValue

0: Vec<u8, Global>
ExtraneousHashReference(HO)

The proof contains at least one extraneous hash reference the should have been omitted.

Tuple Fields of ExtraneousHashReference

0: HO
InvalidChildReference(Vec<u8, Global>)

The proof contains an invalid child reference that exceeds the hash length.

Tuple Fields of InvalidChildReference

0: Vec<u8, Global>
ValueMismatch(Vec<u8, Global>)

The proof indicates that an expected value was not found in the trie.

Tuple Fields of ValueMismatch

0: Vec<u8, Global>
IncompleteProof

The proof is missing trie nodes required to verify.

RootMismatch(HO)

The root hash computed from the proof is incorrect.

Tuple Fields of RootMismatch

0: HO
DecodeError(CE)

One of the proof nodes could not be decoded.

Tuple Fields of DecodeError

0: CE
