source · [−]

    pub fn space0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
        T: InputTakeAtPosition,

Expand description

Recognizes zero or more spaces and tabs.

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> {
        space0(input)
    }

    assert_eq!(parser(" \t21c"), Ok(("21c", " \t")));
    assert_eq!(parser("Z21c"), Ok(("Z21c", "")));
    assert_eq!(parser(""), Ok(("", "")));
