Is it possible to query structures on top of structures?

[Raj2032]

THis seems like a very cool project and I like the fact that it is nosql and it integrates with Rust quite nicely and may be fit for my use case.

I just had a question.

Say I had this code:

struct Customer
{
    id: u16,
    name: Name,
    age: u8,
    is_active: bool,
}

struct Name
{
    first: String,
    last: String,
}

fn main()
{
    let customer = Customer{name: Name{first: "John".to_string(), last: "Doe".to_string()},
    age: 32, is_active: false};
}

I believe it is directly possible to insert from the customer variable after serializing it?

And more importantly how would I query for the first name in my exampel code as name is linked to another structure that contains first and last string data type fields?

Native DB automatically handles calling Native Model to serialize your data. Read these links:

There are no constraints or foreign key principles like in SQL. It is a database that resembles a KV store with some additional functionalities. However, if you want to query your name as a secondary key, you can define your Name struct as a key. Explanation here: ToKey.

@vincent-herlemont Hey mate thanks for your response.

That's great mate.

I see, but as name is wrapped in structure Name, I am not too sure how you would still query any rows with the name "John" without using secondary key, could I get a code example please?
