Function gchemol_parser::parsers::multispace0

pub fn multispace0<T, E>(input: T) -> Result<(T, T), Err<E>> where
    E: ParseError<T>,
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar,
    <T as InputTakeAtPosition>::Item: Clone, 

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

complete version: will return the whole input if no terminating token is found (a non space character).

Example

fn parser(input: &str) -> IResult<&str, &str> {
    multispace0(input)
}

assert_eq!(parser(" \t\n\r21c"), Ok(("21c", " \t\n\r")));
assert_eq!(parser("Z21c"), Ok(("Z21c", "")));
assert_eq!(parser(""), Ok(("", "")));
