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: types.go
    path of file: ./repos/podman/test/tools/vendor/github.com/onsi/ginkgo/v2/types
    
    the code of the file until where you have to start completion: package types

import (
	"encoding/json"
	"fmt"
	"sort"
	"strings"
	"time"
)

const GINKGO_FOCUS_EXIT_CODE = 197
const GINKGO_TIME_FORMAT = "01/02/06 15:04:05.999"

// Report captures information about a Ginkgo test run
type R
    
func (report SpecReport) Labels() []string {
	out := []string{}
	seen := map[string]bool{}
	for _, labels := range report.ContainerHierarchyLabels {
		for _, label := range labels {
			if !seen[label] {
				seen[label] = true
				out = append(out, label)
			}
		}
	}
	for _, label := range report.LeafNodeLabels {
		if !seen[label] {
			seen[label] = true
			out = append(out, label)
		}
	}

	return out
}
