Source

Expand description

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::new(1))));
