Types

type CommunicatorDistributor added in v0.31.0 

type CommunicatorDistributor struct {
	// contains filtered or unexported fields
}

CommunicatorDistributor ingests outbound consensus messages from HotStuff's core logic and distributes them to consumers. This logic only runs inside active consensus participants proposing blocks, voting, collecting + aggregating votes to QCs, and participating in the pacemaker (sending timeouts, collecting + aggregating timeouts to TCs). Concurrently safe.

func NewCommunicatorDistributor added in v0.31.0 

func NewCommunicatorDistributor() *CommunicatorDistributor

func (*CommunicatorDistributor) AddCommunicatorConsumer added in v0.31.0 

func (d *CommunicatorDistributor) AddCommunicatorConsumer(consumer hotstuff.CommunicatorConsumer)

func (*CommunicatorDistributor) OnOwnProposal added in v0.31.0 

func (d *CommunicatorDistributor) OnOwnProposal(proposal *flow.Header, targetPublicationTime time.Time)

type Distributor 

type Distributor struct {
	*FollowerDistributor

type FinalizationDistributor added in v0.17.6 

type FinalizationDistributor struct {
	// contains filtered or unexported fields
