Expand description

Recognizes zero or more octal characters: 0-7

Streaming version: Will return Err(nom::Err::Incomplete(_)) if there’s not enough input data, or if no terminating token is found (a non octal digit character).

§Example

assert_eq!(oct_digit0::<_, (_, ErrorKind)>("21cZ"), Ok(("cZ", "21")));
assert_eq!(oct_digit0::<_, (_, ErrorKind)>("Z21c"), Ok(("Z21c", "")));
assert_eq!(oct_digit0::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
