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

type RuntimeCall: Parameter + Dispatchable<RuntimeOrigin = Self::RuntimeOrigin> + From<Call<Self, I>> + IsType<<Self as Config>::RuntimeCall> + From<Call<Self>>

type RuntimeEvent: From<Event<Self, I>> + IsType<<Self as Config>::RuntimeEvent>

type WeightInfo: WeightInfo

Weight information for extrinsics in this pallet.

type Scheduler: ScheduleAnon<BlockNumberFor<Self>, CallOf<Self, I>, PalletsOriginOf<Self>, Hasher = Self::Hashing> + ScheduleNamed<BlockNumberFor<Self>, CallOf<Self, I>, PalletsOriginOf<Self>, Hasher = Self::Hashing>

The Scheduler.

type Currency: ReservableCurrency<Self::AccountId>

Currency type for this pallet.

type SubmitOrigin: EnsureOriginWithArg<Self::RuntimeOrigin, PalletsOriginOf<Self>, Success = Self::AccountId>

Origin from which proposals may be submitted.

type CancelOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which any vote may be cancelled.

type KillOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which any vote may be killed.

type Slash: OnUnbalanced<NegativeImbalanceOf<Self, I>>

Handler for the unbalanced reduction when slashing a preimage deposit.

type Votes: AtLeast32BitUnsigned + Copy + Parameter + Member + MaxEncodedLen

The counting type for votes. Usually just balance.

type Tally: VoteTally<Self::Votes, TrackIdOf<Self, I>> + Clone + Codec + Eq + Debug + TypeInfo + MaxEncodedLen

The tallying type.

type SubmissionDeposit: Get<BalanceOf<Self, I>>

The minimum amount to be used as a deposit for a public referendum proposal.

type MaxQueued: Get<u32>

Maximum size of the referendum queue for a single track.

type UndecidingTimeout: Get<BlockNumberFor<Self>>

The number of blocks after submission that a referendum must begin being decided by. Once this passes, then anyone may cancel the referendum.

type AlarmInterval: Get<BlockNumberFor<Self>>

Quantization level for the referendum wakeup scheduler. A higher number will result in fewer storage reads/writes needed for smaller voters, but also result in delays to the automatic referendum status changes. Explicit servicing instructions are unaffected.

type Tracks: Get<Vec<(<Self::Tracks as TracksInfo<BalanceOf<Self, I>, BlockNumberFor<Self>>>::Id, TrackInfo<BalanceOf<Self, I>, BlockNumberFor<Self>>)>> + TracksInfo<BalanceOf<Self, I>, BlockNumberFor<Self>, RuntimeOrigin = <Self::RuntimeOrigin as OriginTrait>::PalletsOrigin>

Information concerning the different referendum tracks.

type Preimages: QueryPreimage<H = Self::Hashing> + StorePreimage

The preimage provider.
