Returns the current storage version as supported by the pallet.

fn on_chain_storage_version() -> StorageVersion

Returns the on-chain storage version of the pallet as stored in the storage.

impl<T: Config> IntegrityTest for Module<T>

fn integrity_test()

Run integrity test.

impl<T: Config, D: AsRef<[u8]>> KeyOwnerProofSystem<(KeyTypeId, D)> for Module<T>

type Proof = MembershipProof

The proof of membership itself.

type IdentificationTuple = IdentificationTuple<T>

The full identification of a key owner and the stash account.

fn prove(key: (KeyTypeId, D)) -> Option<Self::Proof>

Prove membership of a key owner in the current block-state.

impl<T: Config> ModuleErrorMetadata for Module<T>

fn metadata() -> &'static [ErrorMetadata]

impl<T: Config + Config> OffchainWorker<<T as Config>::BlockNumber> for Module<T>

fn offchain_worker(_n: BlockNumber)
