请考虑下面的示例代码：

package main

//#include <stdio.h>
//#include <stdint.h>
//#pragma pack(push, 1)
//struct Packed_Struct {
//  uint16_t A;
//  uint16_t B;
//  uint32_t C;
//  uint16_t D;
//};
//#pragma pack(pop)
//
//struct UnPacked_Struct {
//  uint16_t A;
//  uint16_t B;
//  uint32_t C;
//  uint16_t D;
//};
//
//
//void print_C_struct_size(){
//  struct Packed_Struct Packed_Struct;
//  struct UnPacked_Struct UnPacked_Struct;
//  printf("Sizeof Packed_Struct: %lu\n", sizeof(Packed_Struct) );
//  printf("Sizeof UnPacked_Struct: %lu\n", sizeof(UnPacked_Struct) );
//  return;
//}
//
import "C"


import(
    "fmt"
    "unsafe"
)

type GoStruct struct{
    A   uint16
    B   uint16
    C   uint32
    D   uint16
}

func main(){
    fmt.Println("Hello world!")
    meh := C.print_C_struct_size()
    var GoStruct GoStruct
    fmt.Printf("Sizeof GoStruct : %d\n", unsafe.Sizeof(GoStruct) ) 
    fmt.Printf("meh type: %T\n", meh)
}

输出为：

$ go run cgo.go 
Hello world!
Sizeof Packed_Struct: 10
Sizeof UnPacked_Struct: 12
Sizeof GoStruct : 12
meh type: main._Ctype_void

注意，结构体打包时占用10个字节，其他情况下占用12个字节，默认情况下，我在Go语言中的尝试占用了12个字节，如下所示。
有没有一种可行的方法来压缩这个结构体，使它只使用10个字节？
