Struct pallet_message_queue::pallet::Pallet

pub struct Pallet<T>(_);

The pallet implementing the on-chain logic.

Implementations

impl<T: Config> Pallet<T>

pub fn reap_page(
    origin: OriginFor<T>,
    message_origin: MessageOriginOf<T>,
    page_index: u32
) -> DispatchResult

Remove a page which has no more messages remaining to be processed or is stale.

pub fn execute_overweight(
    origin: OriginFor<T>,
    message_origin: MessageOriginOf<T>,
    page: u32,
    index: T::Size,
    weight_limit: Weight
) -> DispatchResultWithPostInfo

Execute an overweight message.

• origin: Must be Signed.
• message_origin: The origin from which the message to be executed arrived.
• page: The page in the queue in which the message to be executed is sitting.
• index: The index into the queue of the message to be executed.
• weight_limit: The maximum amount of weight allowed to be consumed in the execution of the message.

Benchmark complexity considerations: O(index + weight_limit).

impl<T: Config> Pallet<T>

pub fn do_execute_overweight(
    origin: MessageOriginOf<T>,
    page_index: u32,
    index: T::Size,
    weight_limit: Weight
) -> Result<Weight, Error<T>>

Try to execute a single message that was marked as overweight.

The weight_limit is the weight that can be consumed to execute the message. The base weight of the function it self must be measured by the caller.

Examples found in repository

src/lib.rs (line 1262)

	fn execute_overweight(
		weight_limit: Weight,
		(message_origin, page, index): Self::OverweightMessageAddress,
	) -> Result<Weight, ExecuteOverweightError> {
		let mut weight = WeightMeter::from_limit(weight_limit);
		if !weight.check_accrue(
			T::WeightInfo::execute_overweight_page_removed()
				.max(T::WeightInfo::execute_overweight_page_updated()),
		) {
			return Err(ExecuteOverweightError::InsufficientWeight)
		}

		Pallet::<T>::do_execute_overweight(message_origin, page, index, weight.remaining()).map_err(
			|e| match e {
				Error::<T>::InsufficientWeight => ExecuteOverweightError::InsufficientWeight,
				_ => ExecuteOverweightError::NotFound,
			},
		)
	}

pub fn debug_info() -> String

Print the pages in each queue and the messages in each page.

Processed messages are prefixed with a * and the current beginning page with a >.

Example output

queue Here:
  page 0: []
> page 1: []
  page 2: ["\0weight=4", "\0c", ]
  page 3: ["\0bigbig 1", ]
  page 4: ["\0bigbig 2", ]
  page 5: ["\0bigbig 3", ]

Trait Implementations

impl<T: Config> EnqueueMessage<<<T as Config>::MessageProcessor as ProcessMessage>::Origin> for Pallet<T>

type MaxMessageLen = MaxMessageLen<<<T as Config>::MessageProcessor as ProcessMessage>::Origin, <T as Config>::Size, <T as Config>::HeapSize>

The maximal length any enqueued message may have.

fn enqueue_message(
    message: BoundedSlice<'_, u8, Self::MaxMessageLen>,
    origin: <T::MessageProcessor as ProcessMessage>::Origin
)

Enqueue a single message from a specific origin.

fn enqueue_messages<'a>(
    messages: impl Iterator<Item = BoundedSlice<'a, u8, Self::MaxMessageLen>>,
    origin: <T::MessageProcessor as ProcessMessage>::Origin
)

Enqueue multiple messages from a specific origin.

fn sweep_queue(origin: MessageOriginOf<T>)

Any remaining unprocessed messages should happen only lazily, not proactively.

fn footprint(origin: MessageOriginOf<T>) -> Footprint

Return the state footprint of the given queue.

impl<T: Config> GetStorageVersion for Pallet<T>

fn current_storage_version() -> StorageVersion

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> Hooks<<T as Config>::BlockNumber> for Pallet<T>

fn integrity_test()

Check all assumptions about crate::Config.

fn on_initialize(_n: BlockNumberFor<T>) -> Weight

The block is being initialized. Implement to have something happen.

fn on_finalize(_n: BlockNumber)

The block is being finalized. Implement to have something happen.

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

This will be run when the block is being finalized (before on_finalize). Implement to have something happen using the remaining weight. Will not fire if the remaining weight is 0. Return the weight used, the hook will subtract it from current weight used and pass the result to the next on_idle hook if it exists.

fn on_runtime_upgrade() -> Weight

Perform a module upgrade.

fn offchain_worker(_n: BlockNumber)

Implementing this function on a module allows you to perform long-running tasks that make (by default) validators generate transactions that feed results of those long-running computations back on chain.

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

fn integrity_test()

Run integrity test.

impl<T: Config> OffchainWorker<<T as Config>::BlockNumber> for Pallet<T>

fn offchain_worker(n: <T as Config>::BlockNumber)

This function is being called after every block import (when fully synced).
