Function is_not

pub fn is_not<T, Input, Error: ParseError<Input>>(
    arr: T,
) -> impl Fn(Input) -> IResult<Input, <Input as IntoOutput>::Output, Error>
where
    Input: InputTakeAtPosition + IntoOutput,
    T: FindToken<<Input as InputTakeAtPosition>::Item>,

👎Deprecated since 8.0.0: Replaced with nom8::bytes::take_till1 with input wrapped in nom8::input::Streaming

Parse till certain characters are met.

The parser will return the longest slice till one of the characters of the combinator’s argument are met.

It doesn’t consume the matched character.

It will return a Err::Incomplete(Needed::new(1)) if the pattern wasn’t met.

Example

use nom8::bytes::streaming::is_not;

fn not_space(s: &str) -> IResult<&str, &str> {
  is_not(" \t\r\n")(s)
}

assert_eq!(not_space("Hello, World!"), Ok((" World!", "Hello,")));
assert_eq!(not_space("Sometimes\t"), Ok(("\t", "Sometimes")));
assert_eq!(not_space("Nospace"), Err(Err::Incomplete(Needed::new(1))));
assert_eq!(not_space(""), Err(Err::Incomplete(Needed::new(1))));
