}

Implements a traversion over a tree of Element.

All fields of the traversion struct can be mutated, external settings cannot.

Required Methods

fn path_push(&mut self, elem: &'a Element)

push to the traversion path.

fn path_pop(&mut self) -> Option<&'a Element>

pop from the traversion path.

fn get_path(&self) -> &Vec<&'a Element>

get the traversion path.

Provided Methods

fn work( &mut self, _root: &'a Element, _settings: S, _out: &mut dyn Write, ) -> Result<bool>

template method for handling single nodes. if the result is false, handling is complete and children of this node are not considered, otherwise work() is recursively called for all children.

fn work_vec( &mut self, _root: &'a [Element], _settings: S, _out: &mut dyn Write, ) -> Result<bool>

template method for handling a vector of nodes. if the result is false, handling is complete and children of the vector’s elements are not considered, otherwise work() is recursively called for all children.

fn run_vec( &mut self, content: &'a [Element], settings: S, out: &mut dyn Write, ) -> Result<()>

run this traversion for a vector of elements.

fn run( &mut self, root: &'a Element, settings: S, out: &mut dyn Write, ) -> Result<()>

run this traversion for an element.
