Example
package main

import (

	"github.com/zxfonline/atomic"
)

func main() {
	// Uint32 is a thin wrapper around the primitive uint32 type.
	var atom atomic.Uint32

	// The wrapper ensures that all operations are atomic.
	atom.Store(42)
	fmt.Println(atom.Inc())
	fmt.Println(atom.CAS(43, 0))
	bb, _ := atom.MarshalBinary()
	atom.UnmarshalBinary(bb)
	fmt.Println(atom.Load())
