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>>

}

Helper trait for implementing TreeNode that have children stored as Arc’s

If some trait object, such as dyn T, implements this trait, its related Arc 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>>

construct a new self with the specified children
