如何在golang中将regexp放入proto struct中？

syntax = "proto3";

package mypackage;

import "google/protobuf/any.proto";

message MyMessage {
  string regex = 1;
  google.protobuf.Any data = 2;
}

package main

import (
    "fmt"
    "regexp"
    "log"
    "github.com/golang/protobuf/proto"
    "github.com/golang/protobuf/ptypes/any"
    "github.com/mypackage"
)

func main() {
    // 创建一个MyMessage对象
    msg := &mypackage.MyMessage{
        Regex: "ab+c",
        Data:  &any.Any{},
    }

    // 编译正则表达式
    re, err := regexp.Compile(msg.GetRegex())
    if err != nil {
        log.Fatal(err)
    }

    // 使用正则表达式进行匹配
    match := re.MatchString("abbbc")
    fmt.Println(match)
}
