Expand description
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 });
