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))));
