pub fn multispace0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
T: InputTakeAtPosition,
<T as InputTakeAtPosition>::Item: AsChar + Clone, Expand description
Recognizes zero or more spaces, tabs, carriage returns and line feeds.
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!(multispace0::<_, (_, ErrorKind)>(" \t\n\r21c"), Ok(("21c", " \t\n\r")));
assert_eq!(multispace0::<_, (_, ErrorKind)>("Z21c"), Ok(("Z21c", "")));
assert_eq!(multispace0::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));
