package main

import (
  "fmt"
)
  
type CustomOptions struct {
	option1 int
    option2 string
	option3 bool
}

func foo(requiredParam string, optionalParams ...CustomOptions) {
    fmt.Println(len(optionalParams)) // returns how many Custom Options are included
    option1 = optionalParams[0].option1 // params is an array
	fmt.print(optionalParams[0].option1)
}

func main() {
    foo("I'm required")
    foo("I'm required", CustomOptions(option1: 1))
    foo("I'm required", CustomOptions(option1: 1, option2: "2", option3: true))
