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: msghandler.go
    path of file: ./repos/zinx/znet
    
    the code of the file until where you have to start completion: package znet

import (
	"encoding/hex"
	"fmt"
	"sync"

	"github.com/aceld/zinx/z
    
func (mh *MsgHandle) doFuncHandler(request ziface.IFuncRequest, workerID int) {
	defer func() {
		if err := recover(); err != nil {
			zlog.Ins().ErrorF("workerID: %d doFuncRequest panic: %v", workerID, err)
		}
	}()
	// Execute the functional request (执行函数式请求)
	request.CallFunc()
}
