Function `space0`

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

Recognizes zero or more spaces and tabs.

Complete version: Will return the whole input if no terminating token is found (a non space character).

Example

# use nom::{Err, error::ErrorKind, IResult, Needed};
# use nom::character::complete::space0;
fn parser(input: &str) -> IResult<&str, &str> {
    space0(input)
}

assert_eq!(parser(" \t21c"), Ok(("21c", " \t")));
assert_eq!(parser("Z21c"), Ok(("Z21c", "")));
assert_eq!(parser(""), Ok(("", "")));
