pub fn space0<T, E>(input: T) -> Result<(T, T), Err<E>>
Available on crate feature mtls only.
Expand description

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::new(1))));
