[−][src]Function nom::character::streaming::alpha0
pub fn alpha0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
T: InputTakeAtPosition,
<T as InputTakeAtPosition>::Item: AsChar,
Recognizes zero or more lowercase and uppercase alphabetic characters.
- For ASCII strings: a-zA-Z
- For UTF8 strings, any alphabetic code point (ie, not only the ASCII ones)
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::Size(1))));
