Function space0

pub fn space0<T, E: ParseError<T>, const STREAMING: bool>(
    input: T,
) -> IResult<T, <T as IntoOutput>::Output, E>
where
    T: InputTakeAtPosition + InputIsStreaming<STREAMING> + IntoOutput,
    <T as InputTakeAtPosition>::Item: AsChar + Clone,

Recognizes zero or more spaces and tabs.

Complete version: Will return the whole input if no terminating token is found (a non space character).

Streaming version: Will return Err(nom8::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), true>(Streaming(" \t21c")), Ok((Streaming("21c"), " \t")));
assert_eq!(space0::<_, (_, ErrorKind), true>(Streaming("Z21c")), Ok((Streaming("Z21c"), "")));
assert_eq!(space0::<_, (_, ErrorKind), true>(Streaming("")), Err(Err::Incomplete(Needed::new(1))));
