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 Currency: Currency<Self::AccountId> + ReservableCurrency<Self::AccountId>

The staking balance.

source

type ApproveOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which approvals must come.

source

type RejectOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which rejections must come.

source

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

The overarching event type.

source

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

Handler for the unbalanced decrease when slashing for a rejected proposal or bounty.

source

type ProposalBond: Get<Permill>

Fraction of a proposal’s value that should be bonded in order to place the proposal. An accepted proposal gets these back. A rejected proposal does not.

source

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

Minimum amount of funds that should be placed in a deposit for making a proposal.

source

type ProposalBondMaximum: Get<Option<BalanceOf<Self, I>>>

Maximum amount of funds that should be placed in a deposit for making a proposal.

source

type SpendPeriod: Get<BlockNumberFor<Self>>

Period between successive spends.

source

type Burn: Get<Permill>

Percentage of spare funds (if any) that are burnt per spend period.

source

type PalletId: Get<PalletId>

The treasury’s pallet id, used for deriving its sovereign account ID.

source

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

Handler for the unbalanced decrease when treasury funds are burned.

source

type WeightInfo: WeightInfo

Weight information for extrinsics in this pallet.

source

type SpendFunds: SpendFunds<Self, I>

Runtime hooks to external pallet using treasury to compute spend funds.

source

type MaxApprovals: Get<u32>

The maximum number of approvals that can wait in the spending queue.

NOTE: This parameter is also used within the Bounties Pallet extension if enabled.

source

type SpendOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = BalanceOf<Self, I>>

The origin required for approving spends from the treasury outside of the proposal process. The Success value is the maximum amount that this origin is allowed to spend at a time.
