샘플 코드

package main

import (
	"fmt"
	"unsafe"
)

type SSS struct {
	Pointer interface{}
	USafe   unsafe.Pointer
}

func main() {

	num := 10
	sss := "aaaa"

	s1 := SSS{
		Pointer: &num,
		USafe:   unsafe.Pointer(&sss),
	}

	fmt.Printf("%v\n", s1)
	fmt.Printf("%d\n", *(s1.Pointer).(*int))
	fmt.Printf("%s\n", *(*string)(s1.USafe))

	s1.Pointer = &sss
	s1.USafe = unsafe.Pointer(&num)
	fmt.Printf("%v\n", s1)
	fmt.Printf("%s\n", *(s1.Pointer).(*string))
	fmt.Printf("%d\n", *(*int)(s1.USafe))
}
