impl<T: Config> Pallet<T>

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.

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

Cancel an anonymously scheduled task.

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.

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

Cancel a named scheduled task.

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.

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.

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.

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.

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.

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.

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.
