Implementations

impl<T> Pallet<T>

where T: Config,

pub fn schedule( origin: <T as Config>::RuntimeOrigin, when: <<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, maybe_periodic: Option<(<<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, u32)>, priority: u8, call: Box<<T as Config>::RuntimeCall>, ) -> Result<(), DispatchError>

pub fn cancel( origin: <T as Config>::RuntimeOrigin, when: <<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, index: u32, ) -> Result<(), DispatchError>

Cancel an anonymously scheduled task.

pub fn schedule_named( origin: <T as Config>::RuntimeOrigin, id: [u8; 32], when: <<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, maybe_periodic: Option<(<<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, u32)>, priority: u8, call: Box<<T as Config>::RuntimeCall>, ) -> Result<(), DispatchError>

Schedule a named task.

pub fn cancel_named( origin: <T as Config>::RuntimeOrigin, id: [u8; 32], ) -> Result<(), DispatchError>

Cancel a named scheduled task.

pub fn schedule_after( origin: <T as Config>::RuntimeOrigin, after: <<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, maybe_periodic: Option<(<<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, u32)>, priority: u8, call: Box<<T as Config>::RuntimeCall>, ) -> Result<(), DispatchError>

Anonymously schedule a task after a delay.

pub fn schedule_named_after( origin: <T as Config>::RuntimeOrigin, id: [u8; 32], after: <<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, maybe_periodic: Option<(<<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, u32)>, priority: u8, call: Box<<T as Config>::RuntimeCall>, ) -> Result<(), DispatchError>

Schedule a named task after a delay.

pub fn set_retry( origin: <T as Config>::RuntimeOrigin, task: (<<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, u32), retries: u8, period: <<T as Config>::BlockNumberProvider as BlockNumberProvider>::BlockNumber, ) -> Result<(), DispatchError>

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.
