var ErrReceivedSmallerByteOffset = errors.New("Received a smaller byte offset")

ErrReceivedSmallerByteOffset occurs if the ByteOffset received is smaller than a ByteOffset that was set previously

Types

A FlowControlManager manages the flow control

func NewFlowControlManager

func NewFlowControlManager(connectionParameters handshake.ConnectionParametersManager, rttStats *congestion.RTTStats, remoteRTTs map[protocol.PathID]time.Duration) FlowControlManager

NewFlowControlManager creates a new flow control manager

type WindowUpdate

type WindowUpdate struct {
	StreamID protocol.StreamID
	Offset   protocol.ByteCount
}

WindowUpdate provides the data for WindowUpdateFrames.
