Types

type BufferPrefixedConn

type BufferPrefixedConn struct {
	BufferPrefixedReader
	// contains filtered or unexported fields
}

BufferPrefixedConn is a net.Conn with BufferPrefixedReader

func NewBufferPrefixedConn

func NewBufferPrefixedConn(c net.Conn, b []byte) *BufferPrefixedConn

func (*BufferPrefixedConn) Read

func (bc *BufferPrefixedConn) Read(b []byte) (int, error)

type BufferPrefixedReader

type BufferPrefixedReader struct {
	Reader io.Reader
	Buffer []byte
	// contains filtered or unexported fields
}

BufferPrefixedReader is an io.Reader which first read from Buffer, then from another io.Reader

func NewBufferPrefixedReader

func NewBufferPrefixedReader(r io.Reader, b []byte) *BufferPrefixedReader

func (*BufferPrefixedReader) Read

func (br *BufferPrefixedReader) Read(b []byte) (int, error)

Read implements io.Reader

type Datagram

type Datagram interface {
	Data() []byte
	Reply(b []byte) error
	// contains filtered or unexported methods
}

func ReadUDPDatagram

func ReadUDPDatagram(pc net.PacketConn) (Datagram, error)

type DualModeMultiplexedConn

type DualModeMultiplexedConn interface {
	MultiplexedConn
	SeqPacket
}

func WrapQUICConn

func WrapQUICConn(conn quic.Connection) DualModeMultiplexedConn

type MultiplexedConn

type MultiplexedConn interface {
	Accept() (net.Conn, error)
	Dial() (net.Conn, error)
	// contains filtered or unexported methods
}

type NetBufferOnlyReader

type NetBufferOnlyReader struct {
	Conn net.Conn
}

NetBufferOnlyReader is a wrapper over net.Conn which try to only read data which already in OS buffer by setting read timeout to 1us

func (*NetBufferOnlyReader) Read

func (n *NetBufferOnlyReader) Read(b []byte) (int, error)

type SeqPacket

type SeqPacket interface {
	NextDatagram() (Datagram, error)
	Reply(b []byte) error
	// contains filtered or unexported methods
}

func WrapNetConnUDP

func WrapNetConnUDP(conn net.Conn) SeqPacket
