Expand description

Error returned when a trie range proof is invalid.

Variants§

§

NonMonotonicLeaves

The response leaves are not strictly increasing.

§

LeafBeforeOrigin

A returned leaf precedes the requested origin.

Fields

§key: B256

Hashed key of the offending leaf.

§origin: B256

Inclusive origin the range was requested from.

§

EmptyLeafValue

A returned leaf has no value and would represent a deletion.

Fields

§key: B256

Hashed key of the valueless leaf.

§

MissingProofNode

A proof node required on a range boundary is missing.

Fields

§path: Nibbles

Trie path the missing node was referenced from.

§

EmptyExtensionKey

An extension node consumes no nibble, so a crafted chain could recurse without descending.

Fields

§path: Nibbles

Trie path the extension was reached at.

§

PathTooLong

A proof path exceeds a hashed key’s fixed length.

Fields

§path: Nibbles

Trie path that could not be descended any further.

§

InvalidLeafPath

A leaf does not resolve to a complete hashed key.

Fields

§path: Nibbles

Incomplete trie path the leaf terminated at.

§

DuplicateFrontierPath

Two reconstructed trie entries occupy the same path.

Fields

§path: Nibbles

Trie path claimed by more than one entry.

§

RootMismatch

The reconstructed trie does not match the requested root.

Fields

§expected: B256

Root the range was requested against.

§got: B256

Root reconstructed from the response.

§

Rlp(Error)

A trie node failed to decode.
