Required Methods§

Source

fn data(&self) -> &RecognizerData

Source

fn data_mut(&mut self) -> &mut RecognizerData

Provided Methods§

Source

fn add_error_listener<L>(&mut self, listener: L)
where Self: Sized, L: for<'a> ErrorListener<dyn Recognizer + 'a> + Send + 'static,

Adds a listener for syntax and prediction diagnostics.

Recognizers start with one ConsoleErrorListener. Call Self::remove_error_listeners before adding a replacement when diagnostics should not also be written to stderr.
