Signals with Enums?

[floric]

Hey :)

next question, as more people might struggle in the future: somehow it seems like signals support only primitive types like Strings or numeric values. I just tried to fetch a enum like the following in a signal:

pub enum Notification {
    Success(String),
    Warning(String),
    Error(String),
}
...
let (send_alert_message, set_send_alert_message) = create_signal::<Option<Notification>>(cx, None);

When I try to use this signal like here:

{move || {
    if send_alert_message().is_some() {
        view! { cx, <div>"Sent message"</div>}
    } else {
        view! { cx, <div>"Not yet"</div>}
    }
}}

I get the following compiler error:

expected function, found `ReadSignal<Notification>`

If I use a Option<String> instead, it compiles and works as expected. Where is the difference?

Thanks :)

I also found the solution here :)

We need to implement Clone by deriving or implementing it. For me, deriving was enough:

#[derive(Clone)]
pub enum Notification {
    Success(String),
    Warning(String),
    Error(String),
}
