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: image_import.go
    path of file: ./repos/moby/daemon/containerd
    
    the code of the file until where you have to start completion: package containerd

import (
	"bufio"
	"bytes"
	"context"
	"encoding/json"
	"fmt"
	"io"
	"time"

func detectCompression(bufRd *bufio.Reader) (archive.Compression, error) {
	bs, err := bufRd.Peek(10)
	if err != nil && err != io.EOF {
		// Note: we'll ignore any io.EOF error because there are some odd
		// cases where the layer.tar file will be empty (zero bytes) and
		// that results in an io.EOF from the Peek() call. So, in those
		// cases we'll just treat it as a non-compressed stream and
		// that means just create an empty layer.
		// See Issue 18170
		return archive.Uncompressed, errdefs.Unknown(err)
