没有嵌套初始化的golang字段继承

Is it possible to inherit without object initializer?

type BaseEmployee struct{
    LastName string
}

type Employee struct {
 Name string,
 BaseEmployee
}

Right now I have this:

ob := Employee {
  FirstName: "Ron"
  LastName : BaseEmployee {LastName : "Howard"}
}

BUT I want to achieve something like this:

ob := Employee {
  FirstName: "Ron"
  LastName : "Howard",//<<<<<<<<<---- how us that possible?
}

Possible?

    Per the comment left on your question, there is no way to "implicitly" link struct fields to two different structs.

    If it's the struct initialization syntax you object to, you could get around this by just writing a convenience function to initialize a new BaseEmployee, e.g.:

    func NewBaseEmployee(name string) BaseEmployee {
        return BaseEmployee{LastName: name}
    }
    
    ob := Employee {
        FirstName: "Ron"
        LastName : NewBaseEmployee("Howard")
    }
