Required Methods

fn propose_proposal( who: AccountId, threshold: u32, proposal: Box<Proposal>, length_bound: u32, ) -> Result<(u32, u32), DispatchError>

Add a new proposal. Returns a proposal length and active proposals count if successful.

fn vote_proposal( who: AccountId, proposal: Hash, index: ProposalIndex, approve: bool, ) -> Result<bool, DispatchError>

Add an aye or nay vote for the sender to the given proposal. Returns true if the sender votes first time if successful.

fn close_proposal( proposal_hash: Hash, index: ProposalIndex, proposal_weight_bound: Weight, length_bound: u32, ) -> DispatchResultWithPostInfo

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

fn proposal_of(proposal_hash: Hash) -> Option<Proposal>

Return a proposal of the given hash.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
