source · [−]

    pub fn space1<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
        T: InputTakeAtPosition,
        <T as InputTakeAtPosition>::Item: AsChar + Clone,

Expand description

Recognizes one or more spaces and tabs.

Complete version: Will return an error if there’s not enough input data, or the whole input if no terminating token is found (a non space character).

## Example

    fn parser(input: &str) -> IResult<&str, &str> {
        space1(input)
    }

    assert_eq!(parser(" \t21c"), Ok(("21c", " \t")));
    assert_eq!(parser("H2"), Err(Err::Error(Error::new("H2", ErrorKind::Space))));
    assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::Space))));
