Enum PendingChild 

pub enum PendingChild {
    Id(WidgetId),
    Deferred(Box<dyn Widget>),
}

A child that is either pre-registered (ID) or waiting to be inserted. Used by the inline child() builder pattern: deferred children are stored inside the container and resolved recursively when BuildContext::add() inserts the container into the arena.

Variants

Id(WidgetId)

Already in the arena — use this ID directly.

Deferred(Box<dyn Widget>)

Not yet in the arena — insert during resolution.
