import "context"
import "github.com/aws/aws-sdk-go-v2/aws"
import "github.com/aws/aws-sdk-go-v2/config"
import "github.com/aws/aws-sdk-go-v2/service/s3"
import "github.com/aws/aws-sdk-go-v2/feature/s3/manager"

// ...

cfg, err := config.LoadDefaultConfig(context.TODO())
if err != nil {
	log.Println("error:", err)
	return
}

client := s3.NewFromConfig(cfg)

downloader := manager.NewDownloader(client)
numBytes, err := downloader.Download(context.TODO(), downloadFile, &s3.GetObjectInput{
	Bucket: aws.String("my-bucket"), 
	Key:    aws.String("my-key"),
})

The following example uses the Amazon S3 `Downloader` to download a file. Using `Downloader` is similar to the [s3.GetObject](https://pkg.go.dev/github.com/aws/aws-sdk-go-v2/service/s3#Client.GetObject) operation.

The `downloadFile` parameter is an `io.WriterAt` type. The `WriterAt` interface enables the `Downloader` to write multiple parts of the file in parallel.
