pub fn space1<T, E: ParseError<T>, const STREAMING: bool>(
input: T

T: InputTakeAtPosition + InputIsStreaming<STREAMING> + IntoOutput,

Expand description
Recognizes one or more spaces and tabs.
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).
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
fn parser(input: &str) -> IResult<&str, &str> {
space1(input)
}
assert_eq!(parser(" \t21c"), Ok(("21c", " \t")));
assert_eq!(parser("H2"), Err(Err::Error(Error::new("H2", ErrorKind::Space))));
assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::Space))));
assert_eq!(space1::<_, (_, ErrorKind), true>(Streaming(" \t21c")), Ok((Streaming("21c"), " \t")));
assert_eq!(space1::<_, (_, ErrorKind), true>(Streaming("H2")), Err(Err::Error((Streaming("H2"), ErrorKind::Space))));
assert_eq!(space1::<_, (_, ErrorKind), true>(Streaming("")), Err(Err::Incomplete(Needed::new(1))));
