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: checkpoint_list.go
    path of file: ./repos/lazydocker/vendor/github.com/docker/docker/client
    
    the code of the file until where you have to start completion: package client // import "github.com/docker/docker/client"

import (
	"context"
	"encoding/json"
	"net/url"

	"github.com/docker/docker/api/types"
)

// CheckpointList returns the checkpoints of the given container in the docker host
func (cli *Client) CheckpointList(ctx context.Context, container string, options types.CheckpointListOptions) ([]types.Checkpoint, error) {
	var checkpoints [
    
func (cli *Client) CheckpointList(ctx context.Context, container string, options types.CheckpointListOptions) ([]types.Checkpoint, error) {
	var checkpoints []types.Checkpoint

	query := url.Values{}
	if options.CheckpointDir != "" {
		query.Set("dir", options.CheckpointDir)
	}

	resp, err := cli.get(ctx, "/containers/"+container+"/checkpoints", query, nil)
	defer ensureReaderClosed(resp)
	if err != nil {
		return checkpoints, wrapResponseError(err, resp, "container", container)
	}

	err = json.NewDecoder(resp.body).Decode(&checkpoints)
	return checkpoints, err
}
