pub fn apply_update(&mut self, update: NodesStatesUpdate<Key>)
Apply the given NodesStatesUpdate, extending the cached hovered/pressed nodes.
pub fn is_hovered(&self, key: Key) -> bool
Sourcepub fn hovered_nodes(&self) -> impl Iterator<Item = &Key>
pub fn hovered_nodes(&self) -> impl Iterator<Item = &Key>
Nodes currently under the cursor.
