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: main_test.go
    path of file: ./repos/participle/_examples/protobuf
    
    the code of the file until where you have to start completion: package main

import (
	"testing"

	require "github.com/alecthomas/assert/v2"
)

func TestExe(t *testing.T) {
	_, err := parser.ParseString("", `
syn
    
func TestExe(t *testing.T) {
	_, err := parser.ParseString("", `
syntax = "proto3";

package test.test;

message SearchRequest {
  string query = 1;
  int32 page_number = 2;
  int32 result_per_page = 3;
  map<string, double> scores = 4;

  message Foo {}

  enum Bar {
    FOO = 0;
  }
}

message SearchResponse {
  string results = 1;
}

enum Type {
  INT = 0;
  DOUBLE = 1;
}

service SearchService {
  rpc Search(SearchRequest) returns (SearchResponse);
}

	require.NoError(t, err)
}
