Expand description

Utility functions to extend the Tree interface for common operations.

Required Methods§

Source

fn get_element(&self, node_id: &NodeId) -> &Element

Source

fn get_element_mut(&mut self, node_id: &NodeId) -> &mut Element

Source

fn get_parent(&self, child: &NodeId) -> &Element

Source

fn get_parent_mut(&mut self, child: &NodeId) -> &mut Element

Source

fn get_parent_id(&self, child: &NodeId) -> &NodeId

Source

fn splice_subtree( &mut self, parent_id: &NodeId, other: &Tree<Element>, other_id: &NodeId, order: CreateOrder, ) -> NodeId

Splice the subtree of other rooted at other_id into tree under parent_id with the given order

Source

fn write_formatted_names<W: Write>(&self, w: &mut W) -> Result

Write formatted tree representation showing only the names of the nodes (as opposed to the default Tree::write_formatted method).

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
