Struct pallet_collective :: pallet :: Pallet Copy item path

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

pub fn set_members( origin: OriginFor<T>, new_members: Vec<T::AccountId>, prime: Option<T::AccountId>, old_count: MemberCount, ) -> DispatchResultWithPostInfo

Set the collective’s membership.

new_members: The new member list. Be nice to the chain and provide it sorted.
prime: The prime member whose vote sets the default.
old_count: The upper bound for the previous number of members in storage. Used for weight estimation.

The dispatch of this call must be SetMembersOrigin.

NOTE: Does not enforce the expected MaxMembers limit on the amount of members, but the weight estimations rely on it to estimate dispatchable weight.

§WARNING:

The pallet-collective can also be managed by logic outside of the pallet through the implementation of the trait [ChangeMembers]. Any call to set_members must be careful that the member set doesn’t get out of sync with other logic managing the member set.

§Complexity:

O(MP + N) where:
- M old-members-count (code- and governance-bounded)
- N new-members-count (code- and governance-bounded)
- P proposals-count (code-bounded)

pub fn execute( origin: OriginFor<T>, proposal: Box<<T as Config>::Proposal>, length_bound: u32, ) -> DispatchResultWithPostInfo

Dispatch a proposal from a member using the Member origin.

Origin must be a member of the collective.

§Complexity:

O(B + M + P) where:
B is proposal size in bytes (length-fee-bounded)
M members-count (code-bounded)
P complexity of dispatching proposal

pub fn propose( origin: OriginFor<T>, threshold: MemberCount, proposal: Box<<T as Config>::Proposal>, length_bound: u32, ) -> DispatchResultWithPostInfo

Add a new proposal to either be voted on or executed directly.

Requires the sender to be member.

threshold determines whether proposal is executed directly (threshold < 2) or put up for voting.

§Complexity

O(B + M + P1) or O(B + M + P2) where:
- B is proposal size in bytes (length-fee-bounded)
- M is members-count (code- and governance-bounded)
- branching is influenced by threshold where:
 - P1 is proposal execution complexity (threshold < 2)
 - P2 is proposals-count (code-bounded) (threshold >= 2)

pub fn vote( origin: OriginFor<T>, proposal: T::Hash, index: ProposalIndex, approve: bool, ) -> DispatchResultWithPostInfo

Add an aye or nay vote for the sender to the given proposal.

Requires the sender to be a member.

Transaction fees will be waived if the member is voting on any particular proposal for the first time and the call is successful. Subsequent vote changes will charge a fee.

§Complexity

O(M) where M is members-count (code- and governance-bounded)

pub fn disapprove_proposal( origin: OriginFor<T>, proposal_hash: T::Hash, ) -> DispatchResultWithPostInfo

Disapprove a proposal, close, and remove it from the system, regardless of its current state.

Must be called by the Root origin.

Parameters:

proposal_hash: The hash of the proposal that should be disapproved.

§Complexity

O(P) where P is the number of max proposals

pub fn close( origin: OriginFor<T>, proposal_hash: T::Hash, index: ProposalIndex, proposal_weight_bound: Weight, length_bound: u32, ) -> DispatchResultWithPostInfo

Close a vote that is either approved, disapproved or whose voting period has ended.

May be called by any signed account in order to finish voting and close the proposal.

If called before the end of the voting period it will only close the vote if it is has enough votes to be approved or disapproved.

If called after the end of the voting period abstentions are counted as rejections unless there is a prime member set and the prime member cast an approval.

If the close operation completes successfully with disapproval, the transaction fee will be waived. Otherwise execution of the approved operation will be charged to the caller.

proposal_weight_bound: The maximum amount of weight consumed by executing the closed proposal.
length_bound: The upper bound for the length of the proposal in storage. Checked via storage::read so it is size_of::<u32>() == 4 larger than the pure length.

§Complexity

O(B + M + P1 + P2) where:
- B is proposal size in bytes (length-fee-bounded)
- M is members-count (code- and governance-bounded)
- P1 is the complexity of proposal preimage.
- P2 is proposal-count (code-bounded)

pub fn kill( origin: OriginFor<T>, proposal_hash: T::Hash, ) -> DispatchResultWithPostInfo

Disapprove the proposal and burn the cost held for storing this proposal.

Parameters:

origin: must be the KillOrigin.
proposal_hash: The hash of the proposal that should be killed.

Emits Killed and ProposalCostBurned if any cost was held for a given proposal.

pub fn release_proposal_cost( origin: OriginFor<T>, proposal_hash: T::Hash, ) -> DispatchResult

Release the cost held for storing a proposal once the given proposal is completed.

If there is no associated cost for the given proposal, this call will have no effect.

Parameters:

origin: must be Signed or Root.
proposal_hash: The hash of the proposal.

Emits ProposalCostReleased if any cost held for a given proposal.
