Expand description

Recognizes one or more spaces, tabs, carriage returns and line feeds.

Complete version: will return an error if there’s not enough input data, or the whole input if no terminating token is found (a non space character).

§Example

fn parser(input: &str) -> IResult<&str, &str> {
    multispace1(input)
}

assert_eq!(parser(" \t\n\r21c"), Ok(("21c", " \t\n\r")));
assert_eq!(parser("H2"), Err(Err::Error(Error::new("H2", ErrorKind::MultiSpace))));
assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::MultiSpace))));
