[I] [] unmarshal to struct [incubator-fury]
Nyx2022 opened a new issue, #1359:
URL: https://github.com/apache/incubator-fury/issues/1359
## Is your feature request related to a problem? Please describe.
when i marshal a map in java,and send it by internet to a golang program,i only can unmarshal it to a interface{},but i want and need unmarshal it to a struct in golang so that i can get or set attribute easily,but no i unmarshal it to a struct ,i will get a err like:"reflect.Value.IsNil"
## Describe the solution you'd like
support unmarshal to struct in golang
## Additional context

val := event.Query{
Nat: 1,
Ip: "193.1.2.3",
Url: "http://baidu.com",
Status: 0,
}
fury_ := fury.NewFury(true)
if err := fury_.RegisterTagType("example.SomeClass", event.Query{}); err != nil {
panic(err)
}
bt, err := fury_.Marshal(&val)
if err != nil {
b.Log(err)
return
}
_ = fury_.Unmarshal(bt, &newval)
}
报错
panic: reflect.Set: value of type *event.Query is not assignable to type event.Query
而且Readme里的文档 是用interface{}, 不是结构体。
测试无论是序列化反序列化 比Go标准库的json 的时间都不如

@longbai 另外你说的 interface的问题在当前的版本并不存在了：
https://fory.apache.org/docs/next/guide/go/basic_serialization
```go
// Serialize any value
data, err := f.Serialize(value)
if err != nil {
// Handle error
}
// Deserialize into target
var result MyType
err = f.Deserialize(data, &result)
if err != nil {
// Handle error
}
```

@Nyx2022 You can take https://fory.apache.org/docs/next/guide/go/cross_language and https://fory.apache.org/docs/next/guide/xlang/getting_started as references

@longbai 可以再重新试一下，新版本的 fory go 性能比 Protobuf 快2倍，比 msgpack 快11 倍
Benchmark results on Apple M1 Pro:
| Data Type | Operation | Fory (ops/s) | Protobuf (ops/s) | Msgpack (ops/s) | Fory vs PB | Fory vs MP |
| ------------ | ----------- | ------------ | ---------------- | --------------- | ---------- | ---------- |
| Struct | Serialize | 23.52M | 10.83M | 5.19M | 2.17x | 4.54x |
| Struct | Deserialize | 15.01M | 11.97M | 3.28M | 1.25x | 4.58x |
| Sample | Serialize | 8.26M | 3.01M | 750K | 2.75x | 11.01x |
| Sample | Deserialize | 4.52M | 2.51M | 387K | 1.80x | 11.70x |
| Mediacontent | Serialize | 4.93M | 2.30M | 1.17M | 2.14x | 4.21x |
| Mediacontent | Deserialize | 2.74M | 1.87M | 751K | 1.46x | 3.65x |
