Required Methods§

Source

fn get_mut_log(&mut self) -> &mut impl Logger

Gets access to the listener’s log to report possible errors and information about the parsing.

Provided Methods§

Source

fn switch( &mut self, _call: Call, _nt: u16, _alt_id: u16, _t_data: Option<Vec<String>>, )

Calls the listener to execute Enter, Loop, Exit, and End actions.

Source

fn check_abort_request(&self) -> bool

Checks if the wrapper requests an abort. This happens if an error is too difficult to recover from and may corrupt the stack content. In that case, the parser immediately stops and returns ParserError::AbortRequest.
