Types

type AuthRequest

type AuthRequest struct {
	Auth string
	Rx   uint64 // 0 = unknown, client asks server to use bandwidth detection
}

AuthRequest is what client sends to server for authentication.

func AuthRequestFromHeader

func AuthRequestFromHeader(h http.Header) AuthRequest

type AuthResponse

type AuthResponse struct {
	UDPEnabled bool
	Rx         uint64 // 0 = unlimited
	RxAuto     bool   // true = server asks client to use bandwidth detection
}

AuthResponse is what server sends to client when authentication is passed.

func AuthResponseFromHeader

func AuthResponseFromHeader(h http.Header) AuthResponse

type UDPMessage

type UDPMessage struct {
	SessionID uint32 // 4
	PacketID  uint16 // 2
	FragID    uint8  // 1
	FragCount uint8  // 1
	Addr      string // varint + bytes
	Data      []byte
}
