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: pids.go
    path of file: ./repos/podman/vendor/github.com/opencontainers/runc/libcontainer/cgroups/fs
    
    the code of the file until where you have to start completion: package fs

import (
	"math"
	"strconv"

	"github.com/opencontainers/runc/libcontainer/cgroups"
	"github.com/opencontainers/runc/libcontainer/cgroups/fscommon"
	"github.com/opencontainers/runc/libcontainer/configs"
)

type PidsGroup struct{}

func (s *PidsGroup) Name() string {
	return "pids"
}

func (s *PidsGroup) Apply(path string, _ *configs.Resources, pid int) error {
	return apply(path, pid)
}

func (s *PidsGroup) Set(path string, r *configs.Resources) error {
	if r.PidsLimit != 0 {
		// "max" is the fallback value.
		limit := "max"

		if 
    
func (s *PidsGroup) GetStats(path string, stats *cgroups.Stats) error {
	if !cgroups.PathExists(path) {
		return nil
	}
	current, err := fscommon.GetCgroupParamUint(path, "pids.current")
	if err != nil {
		return err
	}

	max, err := fscommon.GetCgroupParamUint(path, "pids.max")
	if err != nil {
		return err
	}
	// If no limit is set, read from pids.max returns "max", which is
	// converted to MaxUint64 by GetCgroupParamUint. Historically, we
	// represent "no limit" for pids as 0, thus this conversion.
	if max == math.MaxUint64 {
		max = 0
	}

	stats.PidsStats.Current = current
	stats.PidsStats.Limit = max
	return nil
}
