Macro unpack_named_slots

macro_rules! unpack_named_slots {
    ($map:expr => $name:ident) => { ... };
    ($map:expr => { $($name:ident),+ }) => { ... };
}

A helper for getting the named children out of a widget context

Example

fn my_component(context: WidgetContext) -> WidgetNode {
    // Destructure our context to get our named slots
    let WidgetContext {
        named_slots,
        ..
    } = context;

    // Unpack our named `body` slot
    unpack_named_slots!(named_slots => body);

    make_widget!(content_box).named_slot("content", body).into()
}

You can also unpack multiple slots at a time like this:

     // Unpack the `header`, `body`, and `footer` slots
     unpack_named_slots!(named_slots => { header, body, footer });
