Struct Nullify 

pub struct Nullify<S: CSignature> {
    pub view: View,
    pub signature: Signature<S>,
}

Nullify represents a validator’s nullify to skip the current view. This is typically used when the leader is unresponsive or fails to propose a valid block.

Fields

view: View

The view to be nullified (skipped)

signature: Signature<S>

The validator’s signature on the view

Implementations

impl<S: CSignature> Nullify<S>

pub fn new(view: View, signature: Signature<S>) -> Self

Creates a new nullify with the given view and signature.

pub fn verify<K: Verifier<Signature = S>>( &self, namespace: &[u8], public_key: &K, ) -> bool

Verifies the signature on this nullify using the provided verifier.

pub fn sign<C: Signer<Signature = S>>( namespace: &[u8], signer: &mut C, public_key_index: u32, view: View, ) -> Self

Creates a new signed nullify using the provided cryptographic scheme.

Trait Implementations

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

fn signer(&self) -> u32

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

impl<S: Clone + CSignature> 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 + CSignature> Debug for Nullify<S>

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

Formats the value using the given formatter.

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

fn encode_size(&self) -> usize

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

impl<S: Hash + CSignature> 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: PartialEq + CSignature> PartialEq for Nullify<S>

fn eq(&self, other: &Nullify<S>) -> 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: CSignature> 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: CSignature> 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: CSignature> Write for Nullify<S>

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

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

impl<S: Eq + CSignature> Eq for Nullify<S>

impl<S: CSignature> StructuralPartialEq for Nullify<S>
