Expand description

Helper trait for implementing TreeNode that have children stored as Arcs. If some trait object, such as dyn T, implements this trait, its related Arc<dyn T> will automatically implement TreeNode.

Required Methods§

source

fn arc_children(&self) -> Vec<Arc<Self>>

Returns all children of the specified TreeNode.

source

fn with_new_arc_children( &self, arc_self: Arc<Self>, new_children: Vec<Arc<Self>> ) -> Result<Arc<Self>, DataFusionError>

Constructs a new node with the specified children.
