Struct pallet_message_queue::pallet::Pallet

pub struct Pallet<T>(_);

The Pallet struct, the main type that implements traits and standalone functions within the pallet.

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.

Temporary processing errors will be propagated whereas permanent errors are treated as success condition.

• 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.

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

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>

type CurrentStorageVersion = NoStorageVersionSet

This will be filled out by the pallet macro.

fn current_storage_version() -> Self::CurrentStorageVersion

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).

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).

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

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

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

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

fn on_genesis()

Something that should happen at genesis.

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

fn on_idle(n: <T as Config>::BlockNumber, remaining_weight: Weight) -> Weight

The block is being finalized. Implement to have something happen in case there is leftover weight. Check the passed remaining_weight to make sure it is high enough to allow for your pallet’s extra computation.

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

fn on_initialize(n: <T as Config>::BlockNumber) -> Weight

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

fn index() -> usize

Index of the pallet as configured in the runtime.

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
