type PacketLossReason

type PacketLossReason uint8

const (
	// PacketLossReorderingThreshold: when a packet is deemed lost due to reordering threshold
	PacketLossReorderingThreshold PacketLossReason = iota
	// PacketLossTimeThreshold: when a packet is deemed lost due to time threshold
	PacketLossTimeThreshold
)

func (PacketLossReason) String

func (r PacketLossReason) String() string

type Tracer

type Tracer interface {
	Export() error
	StartedConnection(t time.Time, local, remote net.Addr, version protocol.VersionNumber, srcConnID, destConnID protocol.ConnectionID)
	SentPacket(t time.Time, hdr *wire.ExtendedHeader, packetSize protocol.ByteCount, ack *wire.AckFrame, frames []wire.Frame)
	ReceivedRetry(time.Time, *wire.Header)
	ReceivedPacket(t time.Time, hdr *wire.ExtendedHeader, packetSize protocol.ByteCount, frames []wire.Frame)
	UpdatedMetrics(t time.Time, rttStats *congestion.RTTStats, cwnd protocol.ByteCount, bytesInFLight protocol.ByteCount, packetsInFlight int)
	LostPacket(time.Time, protocol.EncryptionLevel, protocol.PacketNumber, PacketLossReason)
}

A Tracer records events to be exported to a qlog.

func NewTracer

func NewTracer(w io.WriteCloser, p protocol.Perspective, odcid protocol.ConnectionID) Tracer

NewTracer creates a new tracer to record a qlog.
