Expand description

A visitor for the syntax tree produced by the dice language parser. Each method visits a specific type of node in the syntax tree, and is responsible for visiting any interesting children of that node.

§Type Parameters

  • E: The type of error that can occur while visiting the syntax tree.

Required Methods§

Source

§Parameters
  • node: The “function” node.
§Errors

An error if one occurs while visiting the “function” node.

Source

fn visit_parameters(&mut self, node: &Node<'_>) -> Result<(), E>

Visit a “parameters” node in the syntax tree.

§Parameters
  • node: The “parameters” node.
§Errors

An error if one occurs while visiting the “parameters” node.

Source

fn visit_parameter(&mut self, node: &Node<'_>) -> Result<(), E>

Visit a “parameter” node in the syntax tree.

§Parameters
  • node: The “parameter” node.

Source

fn visit_variable(&mut self, node: &Node<'_>) -> Result<(), E>

Visit a “variable” node in the syntax tree.

§Parameters
  • node: The “variable” node.
§Errors

An error if one occurs while visiting the “variable” node.

Source

fn visit_group(&mut self, node: &Node<'_>) -> Result<(), E>
