    pub fn alpha0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where

Expand description

Recognizes zero or more lowercase and uppercase ASCII alphabetic characters: a-z, A-Z

Complete version: Will return the whole input if no terminating token is found (a non alphabetic character).

## Example

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

    assert_eq!(parser("ab1c"), Ok(("1c", "ab")));
    assert_eq!(parser("1c"), Ok(("1c", "")));
    assert_eq!(parser(""), Ok(("", "")));
