# Function nom::character::streaming::alphanumeric1

source · [−]

    pub fn alphanumeric1<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
        T: InputTakeAtPosition,
        <T as InputTakeAtPosition>::Item: AsChar,

Expand description

Recognizes one or more ASCII numerical and alphabetic characters: 0-9, 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 alphanumerical character).

## Example

    assert_eq!(alphanumeric1::<_, (_, ErrorKind)>("21cZ%1"), Ok(("%1", "21cZ")));
    assert_eq!(alphanumeric1::<_, (_, ErrorKind)>("&H2"), Err(Err::Error(("&H2", ErrorKind::AlphaNumeric))));
    assert_eq!(alphanumeric1::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
