Function nom::character::streaming::space0

pub fn space0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
    T: InputTakeAtPosition,
    <T as InputTakeAtPosition>::Item: AsChar + Clone, 

Recognizes zero 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!(space0::<_, (_, ErrorKind)>(" \t21c"), Ok(("21c", " \t")));
assert_eq!(space0::<_, (_, ErrorKind)>("Z21c"), Ok(("Z21c", "")));
assert_eq!(space0::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::Size(1))));
