是否可以在go插件和应用程序之间共享自定义数据类型？

I know that it is possible to look up for go-plugin symbols that were exported and type assert them into an interface. However, I wonder if is there a way to type assert them into a struct, for example. Is there a way to do it?

For example:

plugin.go

package main

type Person struct {
    Name string
}

var (
    P = Person{
        Name: "Emma",
    }
)

app.go

package main

import (
    "fmt"
    "plugin"
    "os"
)

func main() {
    plug, err := plugin.Open("./plugin.so")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    sym, err := plug.Lookup("P")
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    var p Person
    p, ok := sym.(Person)
    if !ok {
        fmt.Println("Wrong symbol type")
        os.Exit(1)
    }

    fmt.Println(p.Name) 
}

The symbol P, which is a Person, is found when plug.Lookup is called. However, I can't type-assert P into Person, I get an execution time error. In this example, "Wrong symbol type".

Is there a way to achieve this or the only way to share data between the plugin and the application is using interfaces?

Thanks.
