Result of a query on a TrackingCopy.

Variants

RootNotFound

Invalid state root hash.

ValueNotFound(String)

The value wasn’t found.

CircularReference(String)

A circular reference was found in the state while traversing it.

DepthLimit

The query reached the depth limit.

Fields

depth: u64

The depth reached.

Success

The query was successful.

Fields

value: StoredValue

The value read from the state.

proofs: Vec<TrieMerkleProof<Key, StoredValue>>

Merkle proofs for the value.
