type ConnPacketConn ¶ added in v1.38.0

type ConnPacketConn interface {
	net.Conn
	net.PacketConn
}

ConnPacketConn is the interface that's a superset of net.Conn and net.PacketConn.

type HalfCloser ¶ added in v1.104.0

type HalfCloser interface {
	CloseRead() error
	CloseWrite() error
}

HalfCloser is an interface to abstract around various Conn types that allow closing of the read and write streams independently of each other. It is normally used as a typecast for a `net.Conn` to get access to these functions. If you use it for this purpose, you should either be absolutely certain that the `net.Conn` you have represents a half-closable connection (eg. TCP or unix socket), or check for and handle a failure to cast.

type PacketConn ¶ added in v1.30.0

type PacketConn interface {
	WriteToUDPAddrPort([]byte, netip.AddrPort) (int, error)
	ReadFromUDPAddrPort([]byte) (int, netip.AddrPort, error)
	io.Closer
	LocalAddr() net.Addr
	SetDeadline(time.Time) error
	SetReadDeadline(time.Time) error
	SetWriteDeadline(time.Time) error
}

PacketConn is like a net.PacketConn but uses the newer netip.AddrPort write/read methods.

type PacketListener ¶

type PacketListener interface {
	ListenPacket(ctx context.Context, network, address string) (net.PacketConn, error)
}

PacketListener defines the ListenPacket method as implemented by net.ListenConfig, net.ListenPacket, and tstest/natlab.

type PacketListenerWithNetIP ¶ added in v1.30.0

type PacketListenerWithNetIP interface {
	ListenPacket(ctx context.Context, network, address string) (PacketConn, error)
}

func MakePacketListenerWithNetIP(ln PacketListener) PacketListenerWithNetIP

type Std ¶

type Std struct{}

Std implements PacketListener using the Go net package's ListenPacket func.

func (Std) ListenPacket(ctx context.Context, network, address string) (net.PacketConn, error)
