Function `space0`

fn space0<T, E: ParseError<T>>(input: T) -> crate::internal::IResult<T, T, E>
where
    T: Input,
    <T as Input>::Item: AsChar

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

# use nom::{Err, error::ErrorKind, IResult, Needed};
# use nom::character::streaming::space0;
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))));
