Struct Supervisor

pub struct Supervisor { /* private fields */ }

Implementation of commonware_consensus::Supervisor.

Implementations

impl Supervisor

pub fn new( polynomial: Poly<Evaluation>, participants: Vec<PublicKey>, share: Share, ) -> Self

Create a new Supervisor.

Trait Implementations

impl Clone for Supervisor

fn clone(&self) -> Supervisor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Coordinator for Supervisor

type PublicKey = PublicKey

Type used to uniquely identify peers.

fn peers(&self) -> &Vec<Self::PublicKey>

Returns the current list of peers that can be used to fetch data.

fn peer_set_id(&self) -> u64

Returns an identifier for the peer set.

impl Supervisor for Supervisor

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 Supervisor

type Seed = <MinSig as Variant>::Signature

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

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 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).
