Crate sp_transaction_storage_proof

Storage proof primitives. Constains types and basic code to extract storage proofs for indexed transactions.

Modules

• registration

Structs

• InherentDataProvider
  Provider for inherent data.
• 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

• encode_index
  A utility function to encode transaction index as trie key.
• random_chunk
  A utility function to extract a chunk index from the source of randomness.
