# Function nom::character::streaming::space0

source · [−]

    pub fn space0<T, E: ParseError<T>>(input: T) -> IResult<T, T, E> where
        T: InputTakeAtPosition,
        <T as InputTakeAtPosition>::Item: AsChar + Clone,

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))));
