pub fn alpha0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
T: InputTakeAtPosition,
<T as InputTakeAtPosition>::Item: AsChar, Expand description
Recognizes zero or more lowercase and uppercase ASCII alphabetic characters: a-z, A-Z
Streaming version: Will return Err(nom::Err::Incomplete(_)) if there’s not enough input data,
or if no terminating token is found (a non alphabetic character).
Example
assert_eq!(alpha0::<_, (_, ErrorKind)>("ab1c"), Ok(("1c", "ab")));
assert_eq!(alpha0::<_, (_, ErrorKind)>("1c"), Ok(("1c", "")));
assert_eq!(alpha0::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
