impl<T: Config> Pallet<T>

pub fn place_order_allow_death( origin: OriginFor<T>, max_amount: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, para_id: ParaId ) -> DispatchResult

Create a single on demand core order. Will use the spot price for the current block and will reap the account if needed.

Parameters:

origin: The sender of the call, funds will be withdrawn from this account.
max_amount: The maximum balance to withdraw from the origin to place an order.
para_id: A ParaId the origin wants to provide blockspace for.

Errors:

InsufficientBalance: from the Currency implementation

NoOnDemandCores

Events:

pub fn place_order_keep_alive( origin: OriginFor<T>, max_amount: <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, para_id: ParaId ) -> DispatchResult

Same as the place_order_allow_death call , but with a check that placing the order will not reap the account.

Parameters:

origin: The sender of the call, funds will be withdrawn from this account.
max_amount: The maximum balance to withdraw from the origin to place an order.
para_id: A ParaId the origin wants to provide blockspace for.

Errors:

InsufficientBalance: from the Currency implementation

pub fn add_on_demand_assignment( assignment: Assignment, location: QueuePushDirection ) -> Result<(), DispatchError>

Adds an assignment to the on demand queue.

Paramenters:

assignment: The on demand assignment to add to the queue.
location: Whether to push this entry to the back or the front of the queue. Pushing an entry to the front of the queue is only used when the scheduler wants to push back an entry it has already popped. Returns:
The unit type on success.

Errors:

InvalidParaId
QueueFull

pub fn get_queue() -> VecDeque<Assignment>

Getter for the order queue.

pub fn get_affinity_map(para_id: ParaId) -> Option<CoreAffinityCount>

Getter for the affinity tracker.

Trait Implementations§

fn pop_assignment_for_core( core_idx: CoreIndex, previous_para: Option<ParaId> ) -> Option<Assignment>

Take the next queued entry that is available for a given core index. Invalidates and removes orders with a para_id that is not ParaLifecycle::Parathread but only in [0..P] range slice of the order queue, where P is the element that is removed from the order queue.

Parameters:

core_idx: The core index
previous_paraid: Which paraid was previously processed on the requested core. Is None if nothing was processed on the core.

fn push_assignment_for_core(core_idx: CoreIndex, assignment: Assignment)

Push an assignment back to the queue. Typically used on session boundaries. Parameters:

core_idx: The core index
