Trait frame_election_provider_support::InstantElectionProvider

pub trait InstantElectionProvider: ElectionProvider {
    fn elect_with_bounds(
        max_voters: usize,
        max_targets: usize
    ) -> Result<Supports<Self::AccountId>, Self::Error>;
}

A sub-trait of the ElectionProvider for cases where we need to be sure an election needs to happen instantly, not asynchronously.

The same DataProvider is assumed to be used.

Consequently, allows for control over the amount of data that is being fetched from the ElectionProvider::DataProvider.

Required Methods

fn elect_with_bounds(
    max_voters: usize,
    max_targets: usize
) -> Result<Supports<Self::AccountId>, Self::Error>

Elect a new set of winners, but unlike ElectionProvider::elect which cannot enforce bounds, this trait method can enforce bounds on the amount of data provided by the DataProvider.

An implementing type, if itself bounded, should choose the minimum of the two bounds to choose the final value of max_voters and max_targets. In other words, an implementation should guarantee that max_voter and max_targets provided to this method are absolutely respected.
