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: localtime.go
    path of file: ./repos/go-toml
    
    the code of the file until where you have to start completion: package toml

import (
	"fmt"
	"strings"
	"time"

	"github.com/pelletier/go-toml/v2/unstable"
)

// LocalDate represents a calendar day in no specific timezone.
type LocalDate struct {
	Year  int
	Month int
	Day   int
}

// AsTime converts d into a specific time instance at midnight in zone.
func
    
func (d LocalTime) String() string {
	s := fmt.Sprintf("%02d:%02d:%02d", d.Hour, d.Minute, d.Second)

	if d.Precision > 0 {
		s += fmt.Sprintf(".%09d", d.Nanosecond)[:d.Precision+1]
	} else if d.Nanosecond > 0 {
		// Nanoseconds are specified, but precision is not provided. Use the
		// minimum.
		s += strings.Trim(fmt.Sprintf(".%09d", d.Nanosecond), "0")
	}

	return s
}
