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: metadata_bsd.go
    path of file: ./repos/rclone/backend/local
    
    the code of the file until where you have to start completion: //go:build darwin || freebsd || netbsd
// +build darwin freebsd netbsd

package local

import (
	"fmt"
	"syscall"
	"time"

	"github.com/rclone/rclone/fs"
)

// Read the metadata from the file into metadata where possible
func (o *Object) readMetadata
    
func (o *Object) readMetadataFromFile(m *fs.Metadata) (err error) {
	info, err := o.fs.lstat(o.path)
	if err != nil {
		return err
	}
	stat, ok := info.Sys().(*syscall.Stat_t)
	if !ok {
		fs.Debugf(o, "didn't return Stat_t as expected")
		return nil
	}
	m.Set("mode", fmt.Sprintf("%0o", stat.Mode))
	m.Set("uid", fmt.Sprintf("%d", stat.Uid))
	m.Set("gid", fmt.Sprintf("%d", stat.Gid))
	if stat.Rdev != 0 {
		m.Set("rdev", fmt.Sprintf("%x", stat.Rdev))
	}
	setTime := func(key string, t syscall.Timespec) {
		m.Set(key, time.Unix(t.Unix()).Format(metadataTimeFormat))
	}
	setTime("atime", stat.Atimespec)
	setTime("mtime", stat.Mtimespec)
	setTime("btime", stat.Birthtimespec)
	return nil
