Function winnow::bytes::streaming::tag

pub fn tag<T, I, Error: ParseError<I>>(
    tag: T
) -> impl Fn(I) -> IResult<I, <I as Stream>::Slice, Error>where
    I: Stream + Compare<T>,
    T: SliceLen + Clone,

👎Deprecated since 0.1.0: Replaced with <code>winnow::bytes::tag</code> with input wrapped in <code>winnow::Partial</code>

Recognizes a pattern.

The input data will be compared to the tag combinator’s argument and will return the part of the input that matches the argument.

Example

use winnow::bytes::streaming::tag;

fn parser(s: &str) -> IResult<&str, &str> {
  tag("Hello")(s)
}

assert_eq!(parser("Hello, World!"), Ok((", World!", "Hello")));
assert_eq!(parser("Something"), Err(ErrMode::Backtrack(Error::new("Something", ErrorKind::Tag))));
assert_eq!(parser("S"), Err(ErrMode::Backtrack(Error::new("S", ErrorKind::Tag))));
assert_eq!(parser("H"), Err(ErrMode::Incomplete(Needed::new(4))));

WARNING: Deprecated, replaced with winnow::bytes::tag with input wrapped in winnow::Partial
