Struct Nullification 

pub struct Nullification<S: CSignature> {
    pub view: View,
    pub signatures: Vec<Signature<S>>,
}

Nullification represents an aggregated set of nullifies that meets the quorum threshold. When a view is nullified, the consensus moves to the next view.

Fields

view: View

The view that has been nullified

signatures: Vec<Signature<S>>

The set of signatures from validators (must meet quorum threshold)

Implementations

impl<S: CSignature> Nullification<S>

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

Creates a new nullification with the given view and set of signatures.

Warning

The signatures must be sorted by the public key index.

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

Verifies all signatures in this nullification using the provided verifier.

Similar to Notarization::verify, ensures quorum of valid signatures from validators.

Trait Implementations

impl<S: Clone + CSignature> Clone for Nullification<S>

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

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

Formats the value using the given formatter.

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

fn encode_size(&self) -> usize

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

impl<S: Hash + CSignature> Hash for Nullification<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 Nullification<S>

fn eq(&self, other: &Nullification<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 Nullification<S>

type Cfg = usize

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, max_len: &usize) -> Result<Self, Error>

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

impl<S: CSignature> Viewable for Nullification<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 Nullification<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 Nullification<S>

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