Function alpha0

Source 
pub fn alpha0<T, E>(input: T) -> Result<(T, T), Err<E>>
where
    E: ParseError<T>,
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar,
Available on crate feature mtls only.
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))));
