Required Associated Types

type Error

Error type produced during traversal.

Provided Methods

fn visit_node(&mut self, node: &Node) -> Result<(), Self::Error>

Dispatch a single node. Most implementers will not override this and will instead implement the per-variant methods below.

fn visit_nodes(&mut self, nodes: &[Node]) -> Result<(), Self::Error>

Visit a sequence of nodes.

fn document(&mut self, children: &[Node]) -> Result<(), Self::Error>

fn paragraph(&mut self, content: &[Node]) -> Result<(), Self::Error>

fn text(&mut self, _text: &EcoString) -> Result<(), Self::Error>

fn emphasis(&mut self, content: &[Node]) -> Result<(), Self::Error>

fn strong(&mut self, content: &[Node]) -> Result<(), Self::Error>

fn thematic_break(&mut self) -> Result<(), Self::Error>
