Function `alpha0`

fn alpha0<T, E: ParseError<T>>(input: T) -> crate::internal::IResult<T, T, E>
where
    T: Input,
    <T as Input>::Item: AsChar

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

# use nom::{Err, error::ErrorKind, IResult, Needed};
# use nom::character::streaming::alpha0;
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))));
