TransactionStorageProof

Holds a chunk of data retrieved from storage along with a proof that the data was stored at that location in the trie.

Enums

Error

Errors that occur in context of inherents.

InherentError

Errors that can occur while checking the storage proof.

Constants

CHUNK_SIZE

Proof trie value size.

DEFAULT_STORAGE_PERIOD

Storage period for data.

INHERENT_IDENTIFIER

The identifier for the proof inherent.

Traits

IndexedBody

An interface to request indexed data from the client.

TransactionStorageProofInherentData

Auxiliary trait to extract storage proof.

Functions
