impl<W: Write> Visitor for Writer<W>

type Output = ()

The result of visiting an AST.

type Err = Error

An error that visiting an AST might return.

fn finish(self) -> Result

All implementors of Visitor must provide a finish method, which yields the result of visiting the AST or an error.

fn visit_pre(&mut self, ast: &Ast) -> Result

This method is called on an Ast before descending into child Ast nodes.

fn visit_post(&mut self, ast: &Ast) -> Result

This method is called on an Ast after descending all of its child Ast nodes.

fn visit_alternation_in(&mut self) -> Result

This method is called between child nodes of an Alternation.

fn visit_class_set_item_pre( &mut self, ast: &ClassSetItem, ) -> Result<(), Self::Err>

This method is called on every ClassSetItem before descending into child nodes.

fn visit_class_set_item_post( &mut self, ast: &ClassSetItem, ) -> Result<(), Self::Err>

This method is called on every ClassSetItem after descending into child nodes.

fn visit_class_set_binary_op_in( &mut self, ast: &ClassSetBinaryOp, ) -> Result<(), Self::Err>

This method is called between the left hand and right hand child nodes of a ClassSetBinaryOp.

fn start(&mut self)

This method is called before beginning traversal of the AST.

fn visit_concat_in(&mut self) -> Result<(), Self::Err>

This method is called between child nodes of a concatenation.

fn visit_class_set_binary_op_pre( &mut self, _ast: &ClassSetBinaryOp, ) -> Result<(), Self::Err>

This method is called on every ClassSetBinaryOp before descending into child nodes.

fn visit_class_set_binary_op_post( &mut self, _ast: &ClassSetBinaryOp, ) -> Result<(), Self::Err>

This method is called on every ClassSetBinaryOp after descending into child nodes.
