Types

type Codec

type Codec interface {
	// WriteHeader sends protocol tag if needed.
	WriteHeader(w io.Writer) error
	// ReadHeader reads protocol tag if needed.
	ReadHeader(r io.Reader) error
	// Write encode to writer message from given buffer.
	Write(w io.Writer, b *bin.Buffer) error
	// Read fills buffer with received message.
	Read(r io.Reader, b *bin.Buffer) error
}

Codec is MTProto transport protocol encoding abstraction.

type Conn added in v0.12.0

type Conn interface {
	Send(ctx context.Context, b *bin.Buffer) error
	Recv(ctx context.Context, b *bin.Buffer) error
	Close() error
}

Conn is transport connection.

type DialFunc

type DialFunc func(ctx context.Context, network, address string) (net.Conn, error)

DialFunc is functional helper for Dialer.

func (DialFunc) DialContext

func (d DialFunc) DialContext(ctx context.Context, network, address string) (net.Conn, error)

DialContext implements Dialer.

type Dialer

type Dialer interface {
	DialContext(ctx context.Context, network, address string) (net.Conn, error)
}

Dialer dials using a context.

type Handler

type Handler func(ctx context.Context, conn Conn) error

Handler is MTProto server connection handler.

type Server

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

Server is a simple MTProto server.

func (*Server) Addr

func (s *Server) Addr() net.Addr

Addr returns server address.

func (*Server) Close

func (s *Server) Close() error

Close stops server and closes given listener.

func (*Server) Serve

func (s *Server) Serve(ctx context.Context, handler Handler) error

Serve runs server using given listener.
