Required Associated Types

type Node: ParserNodeType<'input>

type Return: Default

Required Methods

fn temp_result(&mut self) -> &mut Self::Return

Temporary storage for ParseTreeVisitor blanket implementation to work

Provided Methods

fn visit( &mut self, node: &<Self::Node as ParserNodeType<'input>>::Type, ) -> Self::Return

fn visit_terminal( &mut self, _node: &TerminalNode<'input, Self::Node>, ) -> Self::Return

Called on terminal(leaf) node

fn visit_error_node( &mut self, _node: &ErrorNode<'input, Self::Node>, ) -> Self::Return

Called on error node

fn visit_children( &mut self, node: &<Self::Node as ParserNodeType<'input>>::Type, ) -> Self::Return

fn aggregate_results( &self, aggregate: Self::Return, next: Self::Return, ) -> Self::Return

fn should_visit_next_child( &self, node: &<Self::Node as ParserNodeType<'input>>::Type, current: &Self::Return, ) -> bool

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.
