Assign a value to a struct which was declare from other package

Here is my code.
I extract my struct OperatInfo to the struct.go and wanna to use this struct in the main package which in worker.go.

struct.go

package batch

type OperatInfo struct {
	eventId string
	hallId string
	userId string
	operating string
	operatingID string
	ip string
}

worker.go

package main

import (
	"time"
	"fmt"
	"strconv"
	"./kernel/api"
	"./kernel/db"
	"./batch/basic"
	"./batch/struct"
)

var operatInfo batch.OperatInfo

func BatchDeposit(eventId string, userId string, hallId string, operating string, operatingID string, ip string) {
    // I get an error here
	operatInfo.eventId = eventId
	operatInfo.hallId = hallId
	operatInfo.userId = userId
	operatInfo.operating = operating
	operatInfo.operatingID = operatingID
	operatInfo.ip = ip
}

I just can't set operatInfo fields.

Any suggestions or tips will helps. Thanks.

Only the fields that starts with an upper case letter are public visible.
To solve your problem you can create getter and setter for each field or rename your fields' struct as follow:

type OperatInfo struct {
    EventId string
    HallId string
    UserId string
    Operating string
    OperatingID string
    Ip string
}
