Types

type EventLoadAdded

type EventLoadAdded struct {
	Hash cid.Cid
}

EventLoadAdded An event triggered when entries have been added

func NewEventLoadAdded

func NewEventLoadAdded(h cid.Cid) *EventLoadAdded

NewEventLoadAdded Creates a new EventLoadAdded event

type EventLoadEnd

type EventLoadEnd struct {
	Logs []ipfslog.Log
}

EventLoadEnd An event triggered when load ended

func NewEventLoadEnd

func NewEventLoadEnd(logs []ipfslog.Log) *EventLoadEnd

NewEventLoadEnd Creates a new EventLoadEnd event

type EventLoadProgress

type EventLoadProgress struct {
	ID            string
	Hash          cid.Cid
	Latest        ipfslog.Entry
	UnknownField4 interface{}
	BufferLength  int
}

EventLoadProgress An event triggered when entries have been loaded

func NewEventLoadProgress

func NewEventLoadProgress(id string, h cid.Cid, latest ipfslog.Entry, unknownField4 interface{}, bufferLength int) *EventLoadProgress

NewEventLoadProgress Creates a new EventLoadProgress event

type ReplicationInfo

type ReplicationInfo interface {
	// GetProgress Get the value of progress
	GetProgress() int

	// GetMax Get the value of max
	GetMax() int

	// GetBuffered Get the value of buffered
	GetBuffered() int

	// GetQueued Get the value of queued
	GetQueued() int

	// IncQueued Increments the value of queued
	IncQueued()

	// Reset Resets all values to 0
	Reset()

	// SetProgress Sets the value of progress
	SetProgress(i int)

	// SetMax Sets the value of max
	SetMax(i int)

	// DecreaseQueued Decrements the value of queued of i
	DecreaseQueued(i int)

	// SetBuffered Sets the value of buffered
	SetBuffered(i int)
}

ReplicationInfo Holds information about the current replication state

func NewReplicationInfo

func NewReplicationInfo() ReplicationInfo

NewReplicationInfo Creates a new ReplicationInfo instance

type Replicator

type Replicator interface {
	events.EmitterInterface

	// Stop Stops the replication
	Stop()

	// Load Loads new data to replicate
	Load(ctx context.Context, cids []cid.Cid)

	// GetQueue Returns the list of CID in the queue
	GetQueue() []cid.Cid

	// GetBufferLen Gets the length of the buffer
	GetBufferLen() int
}

Replicator Replicates stores information among peers
