Macro raui_core::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);

    widget! {
        (content_box {
            // insert our body slot in the content box
            content = {body}
        })
    }
}

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 });
