A trait that a tree builder must implement.

Required Associated Types

type Error

The error type of the tree builder.

type Tree

The type of the tree.

Required Methods

fn open_non_terminal( &mut self, name: &'static str, size_hint: Option<usize>, ) -> Result<(), Self::Error>

Creates a node from a non-terminal name.

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

Closes a non-terminal node.

fn add_token(&mut self, token: &Token<'t>) -> Result<(), Self::Error>

Creates a token node.

fn build(self) -> Result<Self::Tree, Self::Error>

Returns the tree.
