Struct A11yChanges 

pub struct A11yChanges {
    pub changed: Vec<WidgetId>,
    pub roots_changed: bool,
    pub reset: bool,
}

The projected nodes that changed since the last frame.

The backend rebuilds the nodes the changed ids project; reset says the projection must be rebuilt from scratch instead, which happens when too many changes queued in one frame. The ids name widgets that are alive, visible and projected at the moment this value is taken, and each appears once; a widget that a frame removes or hides drops out on its own, and the change to its parent’s child list is what takes it off the tree.

Fields

changed: Vec<WidgetId>

The widgets whose projected nodes must be rebuilt, children included.

roots_changed: bool

Whether the list of projected nodes with no projected ancestor may have changed, which the backend’s own root holds as its children.

reset: bool

Whether the whole projection must be rebuilt from scratch.
