Function combine::parser::combinator::any_send_partial_state

pub fn any_send_partial_state<Input, P>(p: P) -> AnySendPartialStateParser<P> where
    Input: Stream,
    P: Parser<Input>,
    P::PartialState: Send + 'static, 

Returns a parser where P::PartialState is boxed. Useful as a way to avoid writing the type since it can get very large after combining a few parsers.

parser! {
    type PartialState = AnySendPartialState;
    fn example[Input]()(Input) -> (char, char)
    where [ Input: Stream<Token = char> ]
    {
        any_send_partial_state((letter(), letter()))
    }
}

    example().easy_parse("ab"),
