Tried out the new Gemini 2.0 Flash Thinking Model and it's an improvement but still has hallucination issues.
I gave it the challenge to rewrite this code to not have references (and provided the full code with tests)
impl<'a, T, I: Iterator<Item = &'a T>> Iterator for PairwiseResults<'a, T, I> { type Item = Pair<&'a T>; fn next(&mut self) -> Option<Self::Item> { match self.iterator.next() { None => { let result = self.prev.map(Last); self.prev = None; result }, Some(next) => { let temp = self.prev; self.prev = Some(next); match temp { None => Some(First(next)), Some(prev) => Some(Middle(prev, next)) } } } } }

This year, instead of Advent of Code I’m doing CodeCrafters and building a mini Kafka github.com/Wattsy2020/r...
It’s quite interesting, so far I’ve learnt that the Kafka Protocol is a bit janky
Also I’m liking the trait system in Rust, it’s handy to implement a trait for a whole group of types
Implementing a trait for all Vectors of a type that implements that trait. impl<T: ToKafkaBytes> ToKafkaBytes for Vec<T> { // write the length of the array, then each item in the array fn to_kafka_bytes(self) -> impl IntoIterator<Item = u8> { let length = VarInt::new((self.len() + 1) as u32); let vec_as_bytes = self.into_iter().flat_map(|item| item.to_kafka_bytes()); length.to_kafka_bytes().into_iter().chain(vec_as_bytes) } }
