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

source

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

source

type Scheduler: ScheduleNamed<BlockNumberFor<Self>, CallOf<Self>, Self::PalletsOrigin>

The Scheduler.

source

type Preimages: QueryPreimage + StorePreimage

The Preimage provider.

source

type Currency: ReservableCurrency<Self::AccountId> + LockableCurrency<Self::AccountId, Moment = BlockNumberFor<Self>>

Currency type for this pallet.

source

type EnactmentPeriod: Get<BlockNumberFor<Self>>

The period between a proposal being approved and enacted.

It should generally be a little more than the unstake period to ensure that voting stakers have an opportunity to remove themselves from the system in the case where they are on the losing side of a vote.

source

type LaunchPeriod: Get<BlockNumberFor<Self>>

How often (in blocks) new public referenda are launched.

source

type VotingPeriod: Get<BlockNumberFor<Self>>

How often (in blocks) to check for new votes.

source

type VoteLockingPeriod: Get<BlockNumberFor<Self>>

The minimum period of vote locking.

It should be no shorter than enactment period to ensure that in the case of an approval, those successful voters are locked into the consequences that their votes entail.

source

type MinimumDeposit: Get<<<Self as Config>::Currency as Currency<<Self as Config>::AccountId>>::Balance>

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

source

type InstantAllowed: Get<bool>

Indicator for whether an emergency origin is even allowed to happen. Some chains may want to set this permanently to false, others may want to condition it on things such as an upgrade having happened recently.

source

type FastTrackVotingPeriod: Get<BlockNumberFor<Self>>

Minimum voting period allowed for a fast-track referendum.

source

type CooloffPeriod: Get<BlockNumberFor<Self>>

Period in blocks where an external proposal may not be re-submitted after being vetoed.

source

type MaxVotes: Get<u32>

The maximum number of votes for an account.

Also used to compute weight, an overly big value can lead to extrinsic with very big weight: see delegate for instance.

source

type MaxProposals: Get<u32>

The maximum number of public proposals that can exist at any time.

source

type MaxDeposits: Get<u32>

The maximum number of deposits a public proposal may have at any time.

source

type MaxBlacklisted: Get<u32>

The maximum number of items which can be blacklisted.

source

type ExternalOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which the next tabled referendum may be forced. This is a normal “super-majority-required” referendum.

source

type ExternalMajorityOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which the next tabled referendum may be forced; this allows for the tabling of a majority-carries referendum.

source

type ExternalDefaultOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which the next tabled referendum may be forced; this allows for the tabling of a negative-turnout-bias (default-carries) referendum.

source

type SubmitOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = Self::AccountId>

Origin from which the new proposal can be made.

The success variant is the account id of the depositor.

source

type FastTrackOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which the next majority-carries (or more permissive) referendum may be tabled to vote according to the FastTrackVotingPeriod asynchronously in a similar manner to the emergency origin. It retains its threshold method.

source

type InstantOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin from which the next majority-carries (or more permissive) referendum may be tabled to vote immediately and asynchronously in a similar manner to the emergency origin. It retains its threshold method.
