如何索引AWS快照输出？

Question

Here I am printing my snapshots. I posted below what I would like the snapshot print out to look like, and would also like to be able to print individual snapshots. I am not sure how to do this any help would be great.

svc := ec2.New(&aws.Config{Region: "us-east-1"})
params := &ec2.DescribeSnapshotsInput{
    OwnerIDs: []*string{
        aws.String("130300684064"),
    },
}

b, err2 := svc.DescribeSnapshots(params)
if err2 != nil {
    panic(err2)
}
fmt.Printf(awsutil.StringValue(b))

Here is what gets outputted: http://imgur.com/3MnBNXI This is what I would like to be output:

{

Snapshots:

If you want to print the details of the individual snapshots, you can iterate over the response:

resp, err := svc.DescribeSnapshots(params)
if err != nil {
    log.Fatal(err)
}
for i, s := range resp.Snapshots {
    fmt.Printf("Snapshot: %d
", i)
    fmt.Println(s)
}
