Implementations

impl<T: Config> Pallet<T>

pub fn heartbeat( origin: OriginFor<T>, heartbeat: Heartbeat<BlockNumberFor<T>>, _signature: <T::AuthorityId as RuntimeAppPublic>::Signature ) -> DispatchResult

Complexity:

• O(K) where K is length of Keys (heartbeat.validators_len)
  • O(K): decoding of length K

type InCodeStorageVersion = StorageVersion

This type is generated by the pallet macro.

👎Deprecated: This method has been renamed to in_code_storage_version and will be removed after March 2024.

DEPRECATED: Use [Self::current_storage_version] instead.

impl<T: Config> Hooks<<<<T as Config>::Block as HeaderProvider>::HeaderT as Header>::Number> for Pallet<T>

fn offchain_worker(now: BlockNumberFor<T>)

Implementing this function on a pallet allows you to perform long-running tasks that are dispatched as separate threads, and entirely independent of the main blockchain execution.

fn on_initialize(_n: BlockNumber) -> Weight

Block initialization hook. This is called at the very beginning of block execution.

fn on_finalize(_n: BlockNumber)

Block finalization hook. This is called at the very end of block execution.

fn on_idle(_n: BlockNumber, _remaining_weight: Weight) -> Weight

Hook to consume a block’s idle time. This will run when the block is being finalized (before [Hooks::on_finalize]).

fn on_poll(_n: BlockNumber, _weight: &mut WeightMeter)

A hook to run logic after inherent application.

fn on_runtime_upgrade() -> Weight

Hook executed when a code change (aka. a “runtime upgrade”) is detected by the FRAME Executive pallet.

The key type expected.

fn on_genesis_session<'a, I>(validators: I)

where I: Iterator<Item = (&'a T::AccountId, T::AuthorityId)> + 'a,

The given validator set will be used for the genesis session. It is guaranteed that the given validator set will also be used for the second session, therefore the first call to on_new_session should provide the same validator set.

fn on_new_session<'a, I>(_changed: bool, validators: I, _queued_validators: I)

where I: Iterator<Item = (&'a T::AccountId, T::AuthorityId)> + 'a,

Session set has changed; act appropriately. Note that this can be called before initialization of your module.
