Function nom::character::complete::multispace0

pub fn multispace0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar + 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(("", "")));
