Okay, thanks for explaining more.

One more question, if @fieldParentPtr("node", n) is typesafe and can get you a User, the compiler needs to know that the struct has the fields of a User, and that this pointer is indeed pointing at a node field, right? Then why do you need to specify "node" at all?

I think I don't understand Zig at all :)

What if the User is in multiple linked lists?

    const User = struct {
        username: []const u8,
        id: u128,
        age: u7,
        sorted_by_age: std.SinglyLinkedList.Node,
        sorted_by_id: std.SinglyLinkedList.Node,
    };
