You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: buffer.go
    path of file: ./repos/Venom/node
    
    the code of the file until where you have to start completion: package node

import (
	"errors"
	"io"
	"log"
	"sync"

	"github.com/Dliv3/Venom/global"
	"github.com/Dliv3/Venom/protocol"
)

type Buffer struct {
	Chan chan interface{}
}

func NewBuffer() *Buffer {
	return &Buffer{
		Chan: make
    
func (buffer *Buffer) ReadLowLevelPacket() (protocol.Packet, error) {
	packet := <-buffer.Chan
	switch packet.(type) {
	case protocol.Packet:
		return packet.(protocol.Packet), nil
	case error:
		return protocol.Packet{}, io.EOF
	default:
		return protocol.Packet{}, errors.New("Data Type Error")
	}
}
