Trait datafusion_common::tree_node::DynTreeNode

pub trait DynTreeNode {
    // Required methods
    fn arc_children(&self) -> Vec<&Arc<Self>>;
    fn with_new_arc_children(
        &self,
        arc_self: Arc<Self>,
        new_children: Vec<Arc<Self>>,
    ) -> Result<Arc<Self>>;
}

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

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

Returns all children of the specified TreeNode.

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

Constructs a new node with the specified children.
