Can I write require member?

[kyubuns]

V-lang is very good language!!!

Can I write require member in struct?
I think a struct which has default value is nearly equal null. (ex. User{ id: 0 } )
I don't want to exist them same as null.
What do you think?

Example, I want "User must have id".

struct User {
	id int /*  'require' keyword*/
}

fn main() {
	user1 := User{id: 10}
	user2 := User{} // I want this is error
}

Hi @kyubuns

Yes! See this discussion:

#3 (comment)

If a struct has at least one private member (and in your example id is private, since it's the default), it will be impossible to use struct initialization syntax outside the module it's defined in.

So you'll have to provide a constructor method (like new_user() User).

Great.
Thanks!!
