Enum ReplaceItemError 

#[non_exhaustive]
pub enum ReplaceItemError {
    UnknownItem(ItemId),
    NotLightweight(ItemId),
}

Why Scene::replace_item could not swap an item box. Travels inside a ReplaceRejected, which also carries the item.

#[non_exhaustive]: see RestoreError.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnknownItem(ItemId)

No entry with this id.

NotLightweight(ItemId)

The entry is a heavyweight Widget, which holds no SceneItem box. Replace its data with SceneModel::set_payload instead.
