Function combine::chainl1

pub fn chainl1<P, Op>(parser: P, op: Op) -> Chainl1<P, Op> where P: Parser, Op: Parser<Input=P::Input>, Op::Output: FnOnce(P::Output, P::Output) -> P::Output

Parses p 1 or more times separated by op The value returned is the one produced by the left associative application of op
