Struct pallet_staking::CompactAssignments

pub struct CompactAssignments { /* fields omitted */ }

Implementations

impl CompactAssignments

pub fn len(&self) -> usize

Get the length of all the assignments that this type is encoding. This is basically the same as the number of assignments, or the number of voters in total.

pub fn edge_count(&self) -> usize

Get the total count of edges.

pub fn unique_targets(&self) -> Vec<ValidatorIndex>

Get the number of unique targets in the whole struct.

Once presented with a list of winners, this set and the set of winners must be equal.

The resulting indices are sorted.

pub fn average_edge_count(&self) -> usize

Get the average edge count.

impl CompactAssignments

pub fn from_assignment<FV, FT, A>(
    assignments: Vec<Assignment<A, OffchainAccuracy>>,
    index_of_voter: FV,
    index_of_target: FT
) -> Result<Self, Error> where
    A: IdentifierT,
    FV: Fn(&'r A) -> Option<NominatorIndex>,
    FT: Fn(&'r A) -> Option<ValidatorIndex>, 

pub fn into_assignment<A: IdentifierT>(
    self,
    voter_at: impl Fn(NominatorIndex) -> Option<A>,
    target_at: impl Fn(ValidatorIndex) -> Option<A>
) -> Result<Vec<Assignment<A, OffchainAccuracy>>, Error>
