Function nom::character::complete::oct_digit1[−][src]

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

complete version: Will return an error if there’s not enough input data, or the whole input if no terminating token is found (a non octal digit character).

Example

fn parser(input: &str) -> IResult<&str, &str> {
    oct_digit1(input)
}

assert_eq!(parser("21cZ"), Ok(("cZ", "21")));
assert_eq!(parser("H2"), Err(Err::Error(("H2", ErrorKind::OctDigit))));
assert_eq!(parser(""), Err(Err::Error(("", ErrorKind::OctDigit))));
