Go中如何将一个byte数组转成任意指定的类型对象？

package main

import (
	"bytes"
	"encoding/binary"
	"fmt"
)

func main() {
	var num int32 = 12345
	buf := new(bytes.Buffer)

	// 将整数转换成byte数组
	err := binary.Write(buf, binary.LittleEndian, num)
	if err != nil {
		fmt.Println("binary.Write failed:", err)
		return
	}

	// 从byte数组中解析出整数
	var newNum int32
	err = binary.Read(buf, binary.LittleEndian, &newNum)
	if err != nil {
		fmt.Println("binary.Read failed:", err)
		return
	}

	fmt.Printf("Original number: %d\n", num)
	fmt.Printf("Converted number: %d\n", newNum)
}
