Struct script::dom::window::LayoutValue
source · pub struct LayoutValue<T: MallocSizeOf> {
is_valid: Rc<Cell<bool>>,
value: T,
}
Expand description
An instance of a value associated with a particular snapshot of layout. This stored value can only be read as long as the associated layout marker that is considered valid. It will automatically become unavailable when the next layout operation is performed.
