Struct Finalization 

pub struct Finalization<S: CSignature, D: Digest> {
    pub proposal: Proposal<D>,
    pub signatures: Vec<Signature<S>>,
}

Finalization represents an aggregated set of finalizes that meets the quorum threshold. When a proposal is finalized, it becomes the canonical block for its view.

Fields

proposal: Proposal<D>

The proposal that has been finalized

signatures: Vec<Signature<S>>

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

Implementations

impl<S: CSignature, D: Digest> Finalization<S, D>

pub fn new(proposal: Proposal<D>, signatures: Vec<Signature<S>>) -> Self

Creates a new finalization with the given proposal and set of signatures.

Warning

The signatures must be sorted by the public key index.

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

Verifies all signatures in this finalization using the provided verifier.

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

Trait Implementations

impl<S: Clone + CSignature, D: Clone + Digest> Clone for Finalization<S, D>

fn clone(&self) -> Finalization<S, D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug + CSignature, D: Debug + Digest> Debug for Finalization<S, D>

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

Formats the value using the given formatter.

impl<S: CSignature, D: Digest> EncodeSize for Finalization<S, D>

fn encode_size(&self) -> usize

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

impl<S: Hash + CSignature, D: Hash + Digest> Hash for Finalization<S, D>

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, D: PartialEq + Digest> PartialEq for Finalization<S, D>

fn eq(&self, other: &Finalization<S, D>) -> 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, D: Digest> Read for Finalization<S, D>

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, D: Digest> Viewable for Finalization<S, D>

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, D: Digest> Write for Finalization<S, D>

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

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