source · 
pub fn oct_digit0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E>
where
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar,
Expand description

Recognizes zero or more octal characters: 0-7

Complete version: Will return the whole input if no terminating token is found (a non octal digit character).

§Example

fn parser(input: &str) -> IResult<&str, &str> {
    oct_digit0(input)
}

assert_eq!(parser("21cZ"), Ok(("cZ", "21")));
assert_eq!(parser("Z21c"), Ok(("Z21c", "")));
assert_eq!(parser(""), Ok(("", "")));
