T: InputTakeAtPosition,
<T as InputTakeAtPosition>::Item: AsChar + Clone, 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(("", "")));
