Struct Pallet

pub struct Pallet<T, I = ()>(/* private fields */);

The Pallet struct, the main type that implements traits and standalone functions within the pallet.

Implementations

impl<T: Config<I>, I: 'static> Pallet<T, I>

pub fn vote( origin: OriginFor<T>, poll_index: PollIndexOf<T, I>, vote: AccountVote<BalanceOf<T, I>>, ) -> DispatchResult

Vote in a poll. If vote.is_aye(), the vote is to enact the proposal; otherwise it is a vote to keep the status quo.

The dispatch origin of this call must be Signed.

• poll_index: The index of the poll to vote for.
• vote: The vote configuration.

Weight: O(R) where R is the number of polls the voter has voted on.

pub fn delegate( origin: OriginFor<T>, class: ClassOf<T, I>, to: <<T as Config>::Lookup as StaticLookup>::Source, conviction: Conviction, balance: BalanceOf<T, I>, ) -> DispatchResultWithPostInfo

Delegate the voting power (with some given conviction) of the sending account for a particular class of polls.

The balance delegated is locked for as long as it’s delegated, and thereafter for the time appropriate for the conviction’s lock period.

The dispatch origin of this call must be Signed, and the signing account must either:

• be delegating already; or

• have no voting activity (if there is, then it will need to be removed through remove_vote).

• to: The account whose voting the target account’s voting power will follow.

• class: The class of polls to delegate. To delegate multiple classes, multiple calls to this function are required.

• conviction: The conviction that will be attached to the delegated votes. When the account is undelegated, the funds will be locked for the corresponding period.

• balance: The amount of the account’s balance to be used in delegating. This must not be more than the account’s current balance.

Emits Delegated.

Weight: O(R) where R is the number of polls the voter delegating to has voted on. Weight is initially charged as if maximum votes, but is refunded later.

pub fn undelegate( origin: OriginFor<T>, class: ClassOf<T, I>, ) -> DispatchResultWithPostInfo

Undelegate the voting power of the sending account for a particular class of polls.

Tokens may be unlocked following once an amount of time consistent with the lock period of the conviction with which the delegation was issued has passed.

The dispatch origin of this call must be Signed and the signing account must be currently delegating.

• class: The class of polls to remove the delegation from.

Emits Undelegated.

Weight: O(R) where R is the number of polls the voter delegating to has voted on. Weight is initially charged as if maximum votes, but is refunded later.

pub fn unlock( origin: OriginFor<T>, class: ClassOf<T, I>, target: <<T as Config>::Lookup as StaticLookup>::Source, ) -> DispatchResult

Remove the lock caused by prior voting/delegating which has expired within a particular class.

The dispatch origin of this call must be Signed.

• class: The class of polls to unlock.
• target: The account to remove the lock on.

Weight: O(R) with R number of vote of target.

pub fn remove_vote( origin: OriginFor<T>, class: Option<ClassOf<T, I>>, index: PollIndexOf<T, I>, ) -> DispatchResult

Remove a vote for a poll.

If:

• the poll was cancelled, or
• the poll is ongoing, or
• the poll has ended such that
  • the vote of the account was in opposition to the result; or
  • there was no conviction to the account’s vote; or
  • the account made a split vote …then the vote is removed cleanly and a following call to unlock may result in more funds being available.

If, however, the poll has ended and:

• it finished corresponding to the vote of the account, and
• the account made a standard vote with conviction, and
• the lock period of the conviction is not over …then the lock will be aggregated into the overall account’s lock, which may involve overlocking (where the two locks are combined into a single lock that is the maximum of both the amount locked and the time is it locked for).

The dispatch origin of this call must be Signed, and the signer must have a vote registered for poll index.

• index: The index of poll of the vote to be removed.
• class: Optional parameter, if given it indicates the class of the poll. For polls which have finished or are cancelled, this must be Some.

Weight: O(R + log R) where R is the number of polls that target has voted on. Weight is calculated for the maximum number of vote.

pub fn remove_other_vote( origin: OriginFor<T>, target: <<T as Config>::Lookup as StaticLookup>::Source, class: ClassOf<T, I>, index: PollIndexOf<T, I>, ) -> DispatchResult

Remove a vote for a poll.

If the target is equal to the signer, then this function is exactly equivalent to remove_vote. If not equal to the signer, then the vote must have expired, either because the poll was cancelled, because the voter lost the poll or because the conviction period is over.

The dispatch origin of this call must be Signed.

• target: The account of the vote to be removed; this account must have voted for poll index.
• index: The index of poll of the vote to be removed.
• class: The class of the poll.

Weight: O(R + log R) where R is the number of polls that target has voted on. Weight is calculated for the maximum number of vote.
