Function nom::character::streaming::oct_digit1

pub fn oct_digit1<T, E: ParseError<T>>(input: T) -> IResult<T, T, E>
where
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar,

Recognizes one 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_digit1::<_, (_, ErrorKind)>("21cZ"), Ok(("cZ", "21")));
assert_eq!(oct_digit1::<_, (_, ErrorKind)>("H2"), Err(Err::Error(("H2", ErrorKind::OctDigit))));
assert_eq!(oct_digit1::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
