[−][src]Function nom::character::streaming::alphanumeric0

pub fn alphanumeric0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar,

Recognizes zero or more numerical and alphabetic characters.

For ASCII strings: 0-9a-zA-Z
For UTF8 strings, 0-9 and 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 alphanumerical character).

Example

assert_eq!(alphanumeric0::<_, (_, ErrorKind)>("21cZ%1"), Ok(("%1", "21cZ")));
assert_eq!(alphanumeric0::<_, (_, ErrorKind)>("&Z21c"), Ok(("&Z21c", "")));
assert_eq!(alphanumeric0::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::Size(1))));
