I figured out this issue. I was calling the struct and needed to call one
specific element of the struct. Then I assign it to a string.
user, err := user.Current()
if err != nil {
log.Fatal(err)
}
var testuser string = string(user.Username)
if testuser == "root" || testuser == "someuser" {
fmt.Println("You are currently logged in as:" + testuser
+":")
}else {
fmt.Println("You need to be root or someuser to run this program")
os.Exit(1)
}
