Enum commands::parser::Node

pub enum Node {
    Command(CommandNode),
    Parameter(ParameterNode),
    ParameterName(ParameterNameNode),
    Root(RootNode),
}

Enumeration of node types used to have vectors of Node and so on.

Variants

Command	Node variant wrapping a CommandNode.
Parameter	Node variant wrapping a ParameterNode.
ParameterName	Node variant wrapping a ParameterNameNode.
Root	Node variant wrapping a RootNode.

Methods

impl Node

The node in the tree of commands and parameters used in the parser.

This trait defines the core operations which a node must support.

fn node(&self) -> &TreeNode

Get the TreeNode data for a given Node.

fn successors(&self) -> &Vec<Rc<Node>>

Get or calculate successors of this node.
