[−][src]Function gchemol_parser::parsers::space1
pub fn space1<T, E>(input: T) -> Result<(T, T), Err<E>> where
E: ParseError<T>,
T: InputTakeAtPosition,
<T as InputTakeAtPosition>::Item: AsChar,
<T as InputTakeAtPosition>::Item: Clone,
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(("H2", ErrorKind::Space)))); assert_eq!(parser(""), Err(Err::Error(("", ErrorKind::Space))));
