Struct Nullify 

pub struct Nullify<S: Scheme> {
    pub round: Round,
    pub vote: Vote<S>,
}

Validator vote for nullifying the current round, i.e. skip the current round. This is typically used when the leader is unresponsive or fails to propose a valid block.

Fields

round: Round

The round to be nullified (skipped).

vote: Vote<S>

Scheme-specific vote material.

Implementations

impl<S: Scheme> Nullify<S>

pub fn sign<D: Digest>( scheme: &S, namespace: &[u8], round: Round, ) -> Option<Self>

Signs a nullify vote for the given round.

pub fn verify<D: Digest>(&self, scheme: &S, namespace: &[u8]) -> bool

Verifies the nullify vote against the provided signing scheme.

This ensures that the nullify signature is valid for the given round.

pub fn round(&self) -> Round

Returns the round associated with this nullify vote.

Trait Implementations

impl<S: Scheme> Attributable for Nullify<S>

fn signer(&self) -> u32

Returns the index of the signer (validator) who produced this message.

impl<S: Clone + Scheme> Clone for Nullify<S>

fn clone(&self) -> Nullify<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug + Scheme> Debug for Nullify<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: Scheme> EncodeSize for Nullify<S>

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

impl<S: Scheme> Epochable for Nullify<S>

type Epoch = u64

Epoch is the type used to indicate a contiguous sequence of views in which the set of validators is constant.

fn epoch(&self) -> Epoch

Returns the epoch associated with this object.

impl<S: Scheme> Hash for Nullify<S>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<S: Scheme> PartialEq for Nullify<S>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<S: Scheme> Read for Nullify<S>

type Cfg = ()

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(reader: &mut impl Buf, _: &()) -> Result<Self, Error>

Reads a value from the buffer using the provided configuration cfg.

impl<S: Scheme> Viewable for Nullify<S>

type View = u64

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

fn view(&self) -> View

Returns the view associated with this object.

impl<S: Scheme> Write for Nullify<S>

fn write(&self, writer: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.
