go - Default struct values

In Go I get that there are default values for types. Take int in this case which is initialised as a 0.

I have an issue where for me a 0 in an int can be a valid value so I need to check if it's been set by me or initialised as such. Is there any way to tell the difference between them at all?

Considering the following code... I need to be able to tell the difference between testIntOne and testIntTwo but they look the same!

package main

import "log"

type test struct {
    testIntOne int
    testIntTwo int
}

func main() {
    s := test{testIntOne: 0}

    log.Println(s)
}
