Struct substrate_gen::runtime::elections_phragmen::calls::TransactionApi

impl TransactionApi

pub fn vote( &self, votes: Vec<AccountId32>, value: u128 ) -> StaticTxPayload<Vote>

Vote for a set of candidates for the upcoming round of election. This can be called to set the initial votes, or update already existing votes.

Upon initial voting, value units of who’s balance is locked and a deposit amount is reserved. The deposit is based on the number of votes and can be updated over time.

The votes should:

not be empty.
be less than the number of possible candidates. Note that all current members and runners-up are also automatically candidates for the next round.

If value is more than who’s free balance, then the maximum of the two is used.

The dispatch origin of this call must be signed.

Warning

It is the responsibility of the caller to NOT place all of their balance into the lock and keep some for further operations.

We assume the maximum weight among all 3 cases: vote_equal, vote_more and vote_less.

pub fn remove_voter(&self) -> StaticTxPayload<RemoveVoter>

Remove origin as a voter.

This removes the lock and returns the deposit.

The dispatch origin of this call must be signed and be a voter.

pub fn submit_candidacy( &self, candidate_count: u32 ) -> StaticTxPayload<SubmitCandidacy>

Submit oneself for candidacy. A fixed amount of deposit is recorded.

All candidates are wiped at the end of the term. They either become a member/runner-up, or leave the system while their deposit is slashed.

The dispatch origin of this call must be signed.

Warning

Even if a candidate ends up being a member, they must call [Call::renounce_candidacy] to get their deposit back. Losing the spot in an election will always lead to a slash.

The number of current candidates must be provided as witness data.

pub fn renounce_candidacy( &self, renouncing: Renouncing ) -> StaticTxPayload<RenounceCandidacy>

Renounce one’s intention to be a candidate for the next election round. 3 potential outcomes exist:

origin is a candidate and not elected in any set. In this case, the deposit is unreserved, returned and origin is removed as a candidate.
origin is a current runner-up. In this case, the deposit is unreserved, returned and origin is removed as a runner-up.
origin is a current member. In this case, the deposit is unreserved and origin is removed as a member, consequently not being a candidate for the next round anymore. Similar to remove_member, if replacement runners exists, they are immediately used. If the prime is renouncing, then no prime will exist until the next round.

The dispatch origin of this call must be signed, and have one of the above roles.

The type of renouncing must be provided as witness data.

pub fn remove_member( &self, who: AccountId32, slash_bond: bool, rerun_election: bool ) -> StaticTxPayload<RemoveMember>

Remove a particular member from the set. This is effective immediately and the bond of the outgoing member is slashed.

If a runner-up is available, then the best runner-up will be removed and replaces the outgoing member. Otherwise, if rerun_election is true, a new phragmen election is started, else, nothing happens.

If slash_bond is set to true, the bond of the member being removed is slashed. Else, it is returned.

The dispatch origin of this call must be root.

Note that this does not affect the designated block number of the next election.

If we have a replacement, we use a small weight. Else, since this is a root call and will go into phragmen, we assume full block for now.

pub fn clean_defunct_voters( &self, num_voters: u32, num_defunct: u32 ) -> StaticTxPayload<CleanDefunctVoters>

Clean all voters who are defunct (i.e. they do not serve any purpose at all). The deposit of the removed voters are returned.

This is an root function to be used only for cleaning the state.

The dispatch origin of this call must be root.

The total number of voters and those that are defunct must be provided as witness data.
