Function digit0

pub fn digit0<T, E: ParseError<T>>(
    input: T,
) -> IResult<T, <T as IntoOutput>::Output, E>
where
    T: InputTakeAtPosition + IntoOutput,
    <T as InputTakeAtPosition>::Item: AsChar,

👎Deprecated since 8.0.0: Replaced with nom8::character::digit0

Recognizes zero or more ASCII numerical characters: 0-9

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 digit character).

Example

fn parser(input: &str) -> IResult<&str, &str> {
    digit0(input)
}

assert_eq!(parser("21c"), Ok(("c", "21")));
assert_eq!(parser("21"), Ok(("", "21")));
assert_eq!(parser("a21c"), Ok(("a21c", "")));
assert_eq!(parser(""), Ok(("", "")));

WARNING: Deprecated, replaced with nom8::character::digit0
