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 with input wrapped in nom8::input::Streaming

Recognizes zero or more ASCII numerical characters: 0-9

Streaming version: Will return Err(nom8::Err::Incomplete(_)) if there’s not enough input data, or if no terminating token is found (a non digit character).

Example

assert_eq!(digit0::<_, (_, ErrorKind)>("21c"), Ok(("c", "21")));
assert_eq!(digit0::<_, (_, ErrorKind)>("a21c"), Ok(("a21c", "")));
assert_eq!(digit0::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));

WARNING: Deprecated, replaced with nom8::character::digit0 with input wrapped in nom8::input::Streaming
