Implementations§

impl<T: Config> Pallet<T>

source

pub fn schedule( origin: OriginFor<T>, when: BlockNumberFor<T>, maybe_periodic: Option<Period<BlockNumberFor<T>>>, priority: Priority, call: Box<<T as Config>::RuntimeCall> ) -> DispatchResult

Anonymously schedule a task.

source

pub fn cancel( origin: OriginFor<T>, when: BlockNumberFor<T>, index: u32 ) -> DispatchResult

Cancel an anonymously scheduled task.

source

pub fn schedule_named( origin: OriginFor<T>, id: TaskName, when: BlockNumberFor<T>, maybe_periodic: Option<Period<BlockNumberFor<T>>>, priority: Priority, call: Box<<T as Config>::RuntimeCall> ) -> DispatchResult

Schedule a named task.

source

pub fn cancel_named(origin: OriginFor<T>, id: TaskName) -> DispatchResult

Cancel a named scheduled task.

source

pub fn schedule_after( origin: OriginFor<T>, after: BlockNumberFor<T>, maybe_periodic: Option<Period<BlockNumberFor<T>>>, priority: Priority, call: Box<<T as Config>::RuntimeCall> ) -> DispatchResult

Anonymously schedule a task after a delay.

source

pub fn schedule_named_after( origin: OriginFor<T>, id: TaskName, after: BlockNumberFor<T>, maybe_periodic: Option<Period<BlockNumberFor<T>>>, priority: Priority, call: Box<<T as Config>::RuntimeCall> ) -> DispatchResult

Schedule a named task after a delay.

source

pub fn set_retry( origin: OriginFor<T>, task: TaskAddress<BlockNumberFor<T>>, retries: u8, period: BlockNumberFor<T> ) -> DispatchResult

Set a retry configuration for a task so that, in case its scheduled run fails, it will be retried after period blocks, for a total amount of retries retries or until it succeeds.

Tasks which need to be scheduled for a retry are still subject to weight metering and agenda space, same as a regular task. If a periodic task fails, it will be scheduled normally while the task is retrying.

Tasks scheduled as a result of a retry for a periodic task are unnamed, non-periodic clones of the original task. Their retry configuration will be derived from the original task’s configuration, but will have a lower value for remaining than the original total_retries.

source

pub fn set_retry_named( origin: OriginFor<T>, id: TaskName, retries: u8, period: BlockNumberFor<T> ) -> DispatchResult

Service (i.e. execute) the given task, being careful not to overflow the weight counter.

This involves:

  • removing and potentially replacing the Lookup entry for the task.
  • realizing the task’s call which can include a preimage lookup.
  • Rescheduling the task for execution in a later agenda if periodic.
source

pub(crate) fn execute_dispatch( weight: &mut WeightMeter, origin: T::PalletsOrigin, call: <T as Config>::RuntimeCall ) -> Result<DispatchResult, ()>

Make a dispatch to the given call from the given origin, ensuring that the weight counter does not exceed its limit and that it is counted accurately (e.g. accounted using post info if available).

NOTE: Only the weight for this function will be counted (origin lookup, dispatch and the call itself).

Returns an error if the call is overweight.

source

pub(crate) fn schedule_retry( weight: &mut WeightMeter, now: BlockNumberFor<T>, when: BlockNumberFor<T>, agenda_index: u32, task: &ScheduledOf<T>, retry_config: RetryConfig<BlockNumberFor<T>> )

Check if a task has a retry configuration in place and, if so, try to reschedule it.

Possible causes for failure to schedule a retry for a task:

  • there wasn’t enough weight to run the task reschedule logic
  • there was no retry configuration in place
  • there were no more retry attempts left
  • the agenda was full.
source

pub(crate) fn ensure_privilege( left: &<T as Config>::PalletsOrigin, right: &<T as Config>::PalletsOrigin ) -> Result<(), DispatchError>

Ensure that left has at least the same level of privilege or higher than right.

Returns an error if left has a lower level of privilege or the two cannot be compared.
