pub fn space1<T, E>(input: T) -> Result<(T, T), Err<E>>
Available on crate feature mtls only.
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))));
