Struct Notarization 

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

Notarization represents an aggregated set of notarizes that meets the quorum threshold. It includes the proposal and the set of signatures from validators.

Fields

proposal: Proposal<D>

The proposal that has been notarized

signatures: Vec<Signature<S>>

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

Implementations

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

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

Creates a new notarization with the given proposal 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 notarization using the provided verifier.

This ensures that:

1. There are at least threshold valid signatures
2. All signatures are valid
3. All signers are in the validator set

In read_cfg, we ensure that the signatures are sorted by public key index and are unique.

Trait Implementations

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

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

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

Formats the value using the given formatter.

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

fn eq(&self, other: &Notarization<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 Notarization<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 Notarization<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 Notarization<S, D>

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

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