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

Example
fn parser(input: &str) -> IResult<&str, &str> {
alpha0(input)

assert_eq!(parser("1c"), Ok(("1c", "")));
assert_eq!(parser(""), Ok(("", "")));
