Expand description

Configuration trait of this pallet.

The main purpose of this trait is to act as an interface between this pallet and the runtime in which it is embedded in. A type, function, or constant in this trait is essentially left to be configured by the runtime that includes this pallet.

Consequently, a runtime that wants to include this pallet must implement this trait.

Required Associated Types§

Source

type WeightInfo: WeightInfo

Weight information for all calls of this pallet.

Source

type Currency: Mutate<Self::AccountId>

Currency used to pay for on-demand Coretime.

Source

type AdminOrigin: EnsureOrigin<Self::RuntimeOrigin>

The origin for administrating this pallet.

Source

type RelayBlockNumberProvider: BlockNumberProvider

Provider of the current Relay-chain block number.

Source

type PoolCapacityProvider: PoolCapacityProvider

Provider of the on-demand pool capacity.

Source

type PricingProvider: PricingProvider<BalanceOf<Self>>

Provider of the order pricing algorithm.

Source

type OrderQueue: QueueOnDemandOrders<RelayBlockNumberOf<Self>>

Used to instruct the Relay chain to enqueue the orders placed here.

Source

type MaxBatchSize: Get<u32>

Maximum pending batch size. NOTE: Since we don’t do chunking, this number of pending orders needs to fit within a single XCM message. This way on_finalize will never send more than one message. Since this pallet is intended to be a temporary solution, and current (as of September 2026) usage of the on-demand feature is low to moderate, it is expected not to be necessary to extend this functionality to allow more orders in a single block.

Source

type PalletId: Get<PalletId>

Identifier from which the internal Pot is generated.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
