[−][src]Function gchemol_parser::parsers::multispace1
pub fn multispace1<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, tabs, carriage returns and line feeds.
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> { multispace1(input) } assert_eq!(parser(" \t\n\r21c"), Ok(("21c", " \t\n\r"))); assert_eq!(parser("H2"), Err(Err::Error(("H2", ErrorKind::MultiSpace)))); assert_eq!(parser(""), Err(Err::Error(("", ErrorKind::MultiSpace))));
