Struct EpochSupervisor 

pub struct EpochSupervisor { /* private fields */ }

Epoch-based Supervisor for commonware_consensus::aggregation.

Implementations

impl EpochSupervisor

pub fn new(supervisor: Arc<Supervisor>) -> Self

pub async fn update(&self, epoch: Epoch)

Trait Implementations

impl Clone for EpochSupervisor

fn clone(&self) -> EpochSupervisor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Monitor for EpochSupervisor

type Index = u64

Index is the type used to indicate the in-progress consensus decision.

async fn subscribe(&mut self) -> (Self::Index, Receiver<Self::Index>)

Create a channel that will receive updates when the latest index (also provided) changes.

impl Supervisor for EpochSupervisor

type Index = u64

Index is the type used to indicate the in-progress consensus decision.

type PublicKey = PublicKey

Public key used to identify participants.

fn leader(&self, _: Self::Index) -> Option<Self::PublicKey>

Return the leader at a given index for the provided seed.

fn participants(&self, _: Self::Index) -> Option<&Vec<Self::PublicKey>>

Get the sorted participants for the given view. This is called when entering a new view before listening for proposals or votes. If nothing is returned, the view will not be entered.

fn is_participant( &self, _: Self::Index, candidate: &Self::PublicKey, ) -> Option<u32>

impl ThresholdSupervisor for EpochSupervisor

type Identity = <MinSig as Variant>::Public

Identity is the type against which threshold signatures are verified.

type Polynomial = Vec<<MinSig as Variant>::Public>

Polynomial is the group polynomial over which partial signatures are verified.

type Seed = <MinSig as Variant>::Signature

Seed is some random value used to bias the leader selection process.

type Share = Share

Share is the type used to generate a partial signature that can be verified against Identity.

fn leader(&self, _: Self::Index, seed: Self::Seed) -> Option<Self::PublicKey>

Return the leader at a given index over the provided seed.

fn identity(&self) -> &Self::Identity

Returns the static identity of the shared secret (typically the constant term of a polynomial).

fn polynomial(&self, _: Self::Index) -> Option<&Self::Polynomial>

Returns the polynomial over which partial signatures are verified at a given index.

fn share(&self, _: Self::Index) -> Option<&Self::Share>

Returns share to sign with at a given index. After resharing, the share may change (and old shares may be deleted).
