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?

tupleof is probably what you're looking for.
ie.

  new SomeClass(cs.tupleof);

That said, why not have the constructor accept the struct as a parameter?

Because it's implemented not by me, and I do not want to touch its realization.
