Expand description
The state for the quorum proposal task.
Fields§
§latest_proposed_view: TYPES::View
Latest view number that has been proposed for.
proposal_dependencies: BTreeMap<TYPES::View, JoinHandle<()>>
Table for the in-progress proposal dependency tasks.
instance_state: Arc<TYPES::InstanceState>
Immutable instance state
quorum_membership: Arc<TYPES::Membership>
Membership for Quorum Certs/votes
public_key: TYPES::SignatureKey
Our public key
private_key: <TYPES::SignatureKey as SignatureKey>::PrivateKey
Our Private Key
timeout: u64
View timeout from config.
storage: Arc<RwLock<I::Storage>>
This node’s storage ref
consensus: OuterConsensus<TYPES>
Shared consensus task state
id: u64
The node’s id
formed_upgrade_certificate: Option<UpgradeCertificate<TYPES>>
The most recent upgrade certificate this node formed. Note: this is ONLY for certificates that have been formed internally, so that we can propose with them.
Certificates received from other nodes will get reattached regardless of this fields, since they will be present in the leaf we propose off of.
upgrade_lock: UpgradeLock<TYPES, V>
Lock for a decided upgrade
epoch_height: u64
Number of blocks in an epoch, zero means there are no epochs
highest_qc: QuorumCertificate2<TYPES>
The highest_qc we’ve seen at the start of this task

&self,
dependency_type: ProposalDependency,
view_number: TYPES::View,

) -> EventDependency<Arc<HotShotEvent<TYPES>>>
fn create_event_dependency( &self, dependency_type: ProposalDependency, view_number: TYPES::View, event_receiver: Receiver<Arc<HotShotEvent<TYPES>>>, ) -> EventDependency<Arc<HotShotEvent<TYPES>>>
Create an event dependency
sourcefn create_and_complete_dependencies(
&self,
view_number: TYPES::View,
event_receiver: &Receiver<Arc<HotShotEvent<TYPES>>>,
event: Arc<HotShotEvent<TYPES>>,
) -> AndDependency<Vec<Vec<Arc<HotShotEvent<TYPES>>>>>
fn create_and_complete_dependencies( &self, view_number: TYPES::View, event_receiver: &Receiver<Arc<HotShotEvent<TYPES>>>, event: Arc<HotShotEvent<TYPES>>, ) -> AndDependency<Vec<Vec<Arc<HotShotEvent<TYPES>>>>>
Creates the requisite dependencies for the Quorum Proposal task. It also handles any event forwarding.
sourcefn create_dependency_task_if_new(
&mut self,
view_number: TYPES::View,
epoch_number: TYPES::Epoch,
event_receiver: Receiver<Arc<HotShotEvent<TYPES>>>,
event_sender: Sender<Arc<HotShotEvent<TYPES>>>,
event: Arc<HotShotEvent<TYPES>>,
) -> Result<()>
fn create_dependency_task_if_new( &mut self, view_number: TYPES::View, epoch_number: TYPES::Epoch, event_receiver: Receiver<Arc<HotShotEvent<TYPES>>>, event_sender: Sender<Arc<HotShotEvent<TYPES>>>, event: Arc<HotShotEvent<TYPES>>, ) -> Result<()>
Create and store an AndDependency
combining EventDependency
s associated with the
given view number if it doesn’t exist. Also takes in the received event
to seed a
dependency as already completed. This allows for the task to receive a proposable event
without losing the data that it received, as the dependency task would otherwise have no
ability to receive the event and, thus, would never propose.
sourceasync fn update_latest_proposed_view(&mut self, new_view: TYPES::View) -> bool
async fn update_latest_proposed_view(&mut self, new_view: TYPES::View) -> bool
Update the latest proposed view number.

event: Arc<HotShotEvent<TYPES>>,
event_receiver: Receiver<Arc<HotShotEvent<TYPES>>>,
event_sender: Sender<Arc<HotShotEvent<TYPES>>>,
) -> Result<()>
pub async fn handle( &mut self, event: Arc<HotShotEvent<TYPES>>, event_receiver: Receiver<Arc<HotShotEvent<TYPES>>>, event_sender: Sender<Arc<HotShotEvent<TYPES>>>, ) -> Result<()>
Handles a consensus event received on the event stream
sourcepub fn cancel_tasks(&mut self, view: TYPES::View)
pub fn cancel_tasks(&mut self, view: TYPES::View)
Cancel all tasks the consensus tasks has spawned before the given view
