Function pest::state

pub fn state<'i, R: RuleType, F>(
    input: &'i str, 
    f: F
) -> Result<Pairs<'i, R>, Error<'i, R>> where
    F: FnOnce(&mut ParserState<'i, R>, Position<'i>) -> Result<Position<'i>, Position<'i>>, 

Creates a ParserState from a &str, supplying it to a closure f.

Examples

let input = "";
pest::state::<(), _>(input, |_, pos| {
    Ok(pos)
}).unwrap();
