This is a combinator I use all the time, might be useful to see something like it in this crate. It drops a byte at a time until the given parser matches, then returns the result. I don't do parsing in any really performance sensative contexts, this can probably be better implemented. This impl demonstrates the idea. ```rust fn drop_until<'a, T>( parser: fn(&'a str) -> IResult<&'a str, T>, ) -> impl FnMut(&'a str) -> IResult<&'a str, T> { map(many_till(take(1u8), parser), |(_, matched)| matched) } ```
