type Chain

type Chain []string

func (Chain) String

func (c Chain) String() string

type Conn

type Conn interface {
	net.Conn
	Connection
}

type Connection

type Connection interface {

	Alive() bool
	DelayHistory() []DelayHistory
	Dial(metadata *Metadata) (Conn, error)
	LastDelay() uint16
	URLTest(ctx context.Context, url string) (uint16, error)
}

type ProxyAdapter

type ProxyAdapter interface {
	Name() string
	Type() AdapterType
	DialContext(ctx context.Context, metadata *Metadata) (Conn, error)

type UDPPacket

type UDPPacket interface {
	// Data get the payload of UDP Packet
	Data() []byte

	// WriteBack writes the payload with source IP/Port equals addr
	// - variable source IP/Port is important to STUN
	// - if addr is not provided, WriteBack will wirte out UDP packet with SourceIP/Prot equals to origional Target,
	//   this is important when using Fake-IP.
	WriteBack(b []byte, addr net.Addr) (n int, err error)

	// Close closes the underlaying connection.
	Close() error
