Function combine::between

pub fn between<I, L, R, P>(open: L, close: R, parser: P) -> Between<L, R, P> where I: Stream, L: Parser<Input=I>, R: Parser<Input=I>, P: Parser<Input=I>

Parses open followed by parser followed by close Returns the value of parser

let result = between(token('['), token(']'), string("rust"))
    .parse("[rust]")
    .map(|x| x.0);
assert_eq!(result, Ok("rust"));
