Function parse_interactive 

pub fn parse_interactive<'p>(
    job: ParseJob<'p, '_>,
) -> Result<InteractiveParser<'p>, ParseError>

Begin an interactive parse (Lark’s parse_interactive): returns immediately with an interactive::InteractiveParser holding the start state and a lazy lexer cursor over text; nothing is lexed until the caller drives it (exhaust_lexer/resume_parse/manual feeds). The returned parser borrows lexer and text for 'p. postlex, when present, is started once (its session interposes between lexer and parser, buffering the fan-out); a non-clonable session is dropped on copy().
