Function gchemol_parser::parsers::streaming::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.

streaming version: Will return Err(nom::Err::Incomplete(_)) if there's not enough input data, or if no terminating token is found (a non space character).

Example

assert_eq!(space1::<_, (_, ErrorKind)>(" \t21c"), Ok(("21c", " \t")));
assert_eq!(space1::<_, (_, ErrorKind)>("H2"), Err(Err::Error(("H2", ErrorKind::Space))));
assert_eq!(space1::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::Size(1))));
