Convert struct to set of fields and pass it's to constructor

[Suliman via Digitalmars-d-learn]

Class constructor accept only set if fields like
this(string login, string pass)
Can I create structure, fill it, and than pass to constructor?

Like this:
```
import std.stdio;

struct ConnectSettings
{
        string login;
        string pass;
};
ConnectSettings cs;

void main()
{
 cs.login = "admin";
 cs.pass = "mypass";
}
```

and than pass to constructor it's like:

`... new SomeClass(cs)`


I tried, but get error, that ctor accept only fields list. Can I 
unroll struct to it?
