Method parse

pest/src/pratt_parser.rs:325–327

The last method to call on the provided pairs to execute the Pratt parser (previously defined using [`map_primary`], [`map_prefix`], [`map_postfix`], and [`map_infix`] methods). # Panics Panics if the input pairs contain a prefix operator with no [`map_prefix`], an infix operator with no [`map_infix`], a postfix operator with no [`map_postfix`], or an unexpected token that is not a valid prefix,

(&mut self, pairs: P)

    /// [`map_postfix`]: struct.PrattParserMap.html#method.map_postfix
    /// [`map_infix`]: struct.PrattParserMap.html#method.map_infix
    pub fn parse<P: Iterator<Item = Pair<'i, R>>>(&mut self, pairs: P) -> T {
        self.expr(&mut pairs.peekable(), 0)
    }

    fn expr<P: Iterator<Item = Pair<'i, R>>>(&mut self, pairs: &mut Peekable<P>, rbp: Prec) -> T {
        let mut lhs = self.nud(pairs);
