Trait Implementations

impl<TYPES: NodeType, THRESHOLD: Threshold<TYPES>> Certificate<TYPES, DaData> for SimpleCertificate<TYPES, DaData, THRESHOLD>

fn stake_table_entry<MEMBERSHIP: Membership<TYPES>>( membership: &MEMBERSHIP, pub_key: &TYPES::SignatureKey, epoch: TYPES::Epoch, ) -> Option<<TYPES::SignatureKey as SignatureKey>::StakeTableEntry>

Proxy’s to Membership.stake

fn stake_table<MEMBERSHIP: Membership<TYPES>>( membership: &MEMBERSHIP, epoch: TYPES::Epoch, ) -> Vec<<TYPES::SignatureKey as SignatureKey>::StakeTableEntry>

Proxy’s to Membership.da_stake_table

fn total_nodes<MEMBERSHIP: Membership<TYPES>>( membership: &MEMBERSHIP, epoch: TYPES::Epoch, ) -> usize

Proxy’s to Membership.da_total_nodes

type Voteable = DaData

The data commitment this certificate certifies.

type Threshold = THRESHOLD

Threshold Functions

fn create_signed_certificate<V: Versions>( vote_commitment: Commitment<VersionedVoteData<TYPES, DaData, V>>, data: Self::Voteable, sig: <TYPES::SignatureKey as SignatureKey>::QcType, view: TYPES::View, ) -> Self

Build a certificate from the data commitment and the quorum of signers

async fn is_valid_cert<V: Versions>( &self, stake_table: Vec<<TYPES::SignatureKey as SignatureKey>::StakeTableEntry>, threshold: NonZeroU64, upgrade_lock: &UpgradeLock<TYPES, V>, ) -> bool

Checks if the cert is valid in the given epoch

fn threshold<MEMBERSHIP: Membership<TYPES>>( membership: &MEMBERSHIP, epoch: TYPES::Epoch, ) -> u64

Returns the amount of stake needed to create this certificate

fn data(&self) -> &Self::Voteable

Get the commitment which was voted on

async fn data_commitment<V: Versions>( &self, upgrade_lock: &UpgradeLock<TYPES, V>, ) -> Result<Commitment<VersionedVoteData<TYPES, DaData, V>>>

Get the vote commitment which the votes commit to

impl Clone for DaData

fn clone(&self) -> DaData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Committable for DaData

fn commit(&self) -> Commitment<Self>

Create a binding commitment to self.

fn tag() -> String

Tag that should be used when serializing commitments to this type.

impl Debug for DaData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DaData

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DaData

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 PartialEq for DaData

fn eq(&self, other: &DaData) -> 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 Serialize for DaData

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DaData
