fn schedule_named( id: Vec<u8>, when: DispatchTime<BlockNumber>, maybe_periodic: Option<(BlockNumber, u32)>, priority: u8, origin: RuntimeOrigin, call: Call, ) -> Result<Self::Address, ()>
v3
instead. Will be removed after September 2024.Schedule a dispatch to happen at the beginning of some block in the future.
id
: The identity of the task. This must be unique and will return an error if not.
fn cancel_named(id: Vec<u8>) -> Result<(), ()>
๐Deprecated: Use v3
instead. Will be removed after September 2024.
fn cancel_named(id: Vec<u8>) -> Result<(), ()>
v3
instead. Will be removed after September 2024.Cancel a scheduled, named task. If periodic, then it will cancel all further instances of that, also.
Will return an error if the id
is invalid.
NOTE: This guaranteed to work only before the point that it is due to be executed. If it ends up being delayed beyond the point of execution, then it cannot be cancelled.
fn reschedule_named(
id: Vec<u8>,
when: DispatchTime<BlockNumber>,
) -> Result<Self::Address, DispatchError>
๐Deprecated: Use v3
instead. Will be removed after September 2024.
fn reschedule_named( id: Vec<u8>, when: DispatchTime<BlockNumber>, ) -> Result<Self::Address, DispatchError>
v3
instead. Will be removed after September 2024.Reschedule a task. For one-off tasks, this dispatch is guaranteed to succeed only if it is executed before the currently scheduled block.
fn next_dispatch_time(id: Vec<u8>) -> Result<BlockNumber, ()>
๐Deprecated: Use v3
instead. Will be removed after September 2024.
fn next_dispatch_time(id: Vec<u8>) -> Result<BlockNumber, ()>
v3
instead. Will be removed after September 2024.Return the next dispatch time for a given task.
Will return an error if the id
is invalid.
