Required Associated Types

type Vote: Send + 'static

type Output: Send + 'static

Required Methods

fn new(m: EpochMembership<T>, l: UpgradeLock<T>) -> Self

fn add(&mut self, vote: Self::Vote) -> Option<Self::Output>

fn min_votes(&self) -> usize

fn has_signer(m: &EpochMembership<T>, signer: &T::SignatureKey) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<T, V, Th> Tally<T> for SimpleTally<T, V, Th>

where T: NodeType, V: Vote<T> + Send + 'static, V::Commitment: 'static, Th: Threshold<T> + Send + 'static, SimpleCertificate<T, <V as Vote<T>>::Commitment, Th>: Certificate<T, V::Commitment, Voteable = V::Commitment> + HasEpoch + Send + 'static,

type Vote = V

type Output = ValidCert<SimpleCertificate<T, <V as Vote<T>>::Commitment, Th>>

impl<T: NodeType, Th: Threshold<T> + Send + 'static> Tally<T> for TimeoutTally<T, Th>

type Vote = TimeoutBallot<T>

type Output = ValidCert<TimeoutCertificate3<T>>

impl<T: NodeType> Tally<T> for EpochRootTally<T>

type Vote = Vote1<T>

type Output = (ValidCert<SimpleCertificate<T, QuorumData2<T>, SuccessThreshold>>, LightClientStateUpdateCertificateV2<T>)
