        mode = "read-write"

2.开始使用

package main

import (
	"context"
	"github.com/dobyte/due/v2/config"
	"github.com/dobyte/due/v2/config/file"
	"github.com/dobyte/due/v2/log"
	"time"
)

func main() {
	ctx := context.Background()
	filepath := "config.toml"

	// 设置全局配置器
	config.SetDefaultConfigurator()

	// 更新配置
	if err := config.Store(ctx, file.Name, filepath, map[string]interface{}{
		"timezone": "Local",
	}); err != nil {
		log.Errorf("store config failed: %v", err)
		return
	}

	time.Sleep(time.Millisecond)

	// 读取配置
	timezone := config.Get("config.timezone", "UTC").String()
	log.Infof("timezone: %s", timezone)

	// 更新配置
	if err := config.Store(ctx, file.Name, filepath, map[string]interface{}{
		"timezone": "UTC",
	}); err != nil {
		log.Errorf("store config failed: %v", err)
		return
	}

	time.Sleep(time.Millisecond)

	// 读取配置
