Types

type Map

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

func New

func New() *Map

New creates a new Map.

func (*Map) Drop

func (m *Map) Drop(seqno uint16, pid uint16) bool

Drop attempts to record a dropped packet. It returns true if the packet is safe to drop.

func (*Map) Map

func (m *Map) Map(seqno uint16, pid uint16) (bool, uint16, uint16)

Map maps a seqno, adding the mapping if required. It returns whether the seqno could be mapped, the target seqno, and the pid delta to apply.

func (*Map) Reverse

func (m *Map) Reverse(seqno uint16) (bool, uint16, uint16)

Reverse maps a target seqno to the original seqno. It returns true if the seqno could be mapped, the original seqno, and the pid delta to apply in reverse.
