pub fn alpha1<T, E: ParseError<T>>(
input: T
) -> IResult<T, <T as Stream>::Slice, E>where
T: Stream,
<T as Stream>::Token: AsChar,👎Deprecated since 0.1.0: Replaced with <code>winnow::character::alpha1</code>
Expand description
Recognizes one or more lowercase and uppercase ASCII alphabetic characters: a-z, A-Z
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 alphabetic character).
Example
fn parser(input: &str) -> IResult<&str, &str> {
alpha1(input)
}
assert_eq!(parser("aB1c"), Ok(("1c", "aB")));
assert_eq!(parser("1c"), Err(ErrMode::Backtrack(Error::new("1c", ErrorKind::Alpha))));
assert_eq!(parser(""), Err(ErrMode::Backtrack(Error::new("", ErrorKind::Alpha))));WARNING: Deprecated, replaced with winnow::character::alpha1
