Go SDK中的DynamoDB查询`--limit 1`？

What's the go-sdk equivalent of --limit 1?

I can do in CLI like:

aws dynamodb query 
  --table-name TABLE_NAME
    ...
  --limit 1

I wasn't sure how to do this in go-SDK, I tried below:

var parameter = &dynamodb.QueryInput{
    TableName: aws.String("TABLE_NAME"),
    KeyConditions: map[string]*dynamodb.Condition{...},
    SetLimit: aws.String("1"),
}
response, err := Dyna.Db.Query(parameter)

Then I had an error like:

$ go test
# _/home/test/
./test.go:48:11: unknown field 'SetLimit' in struct literal of type dynamodb.QueryInput

What's the correct way of --limit 1 in go-SDK?
