Can't access record members [Answered]

I have a record that looks like this

public readonly record struct Card(Suite suite, Rank rank);

public readonly record struct Card(Suite suite, Rank rank);

And am making a record that looks like this

public readonly record struct StandardCard<Card> {
    public readonly Card card;

    public StandardCard(Card card) {
        this.card = card;
    }
}

public readonly record struct StandardCard<Card> {
    public readonly Card card;

    public StandardCard(Card card) {
        this.card = card;
    }
}

I'm new to messing with records, so can't figure something out. Why can't I do card.suite or card.rank in that constructor? I can do it elsewhere in my doe, but not here.

why do you need the record to look like that specifically? why can't you do public readonly record struct StandardCard<Card>(Card card);? nevermind the fact that you use absolutely incorrect naming, and the fact that a generic param on StandardCard is probably just wrong

I think you might be confusing generics here with what you actually want. Is Card meant to be a type parameter of StandardCard or its own type? Because StandardCard<Card> will make Card into a type parameter

Ah. I completely autopiloted making it of that type. Learning functional programming and it's a lot to take in catsweat
