Function nom::character::complete::oct_digit1
source · pub fn oct_digit1<T, E: ParseError<T>>(input: T) -> IResult<T, T, E>
Expand description
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(Error::new("H2", ErrorKind::OctDigit))));
assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::OctDigit))));
